Their noise-shaping behavior results in low output distortion for output frequencies well below the modulation frequency. To directly generate the switch control signals of a traditional DC-DC converter, a first-order modulator with a two-level quantizer is preferred as they are inherently stable for the entire output range. However, the noise attenuation of a first-order modulator is limited to 20dB per decade for frequencies below the modulation frequency. Additionally, they suffer from limit cycles due to the low modulator order and 2-level quantizer resolution. To overcome this problem, a fast feedback loop is proposed that acts on disturbances introduced by the quantizer and compensates low frequency noise. As a result, an improved Delta-Sigma modulator is obtained that remains stable for almost the entire output range but also provides improved noise attenuation like that of a second-order modulator. Moreover, the output noise signature is whitened resulting in less power being present at the limit cycle frequencies.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123185557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Insulation structure is the bottleneck of DC-DC module in SST from insulation effectiveness, manufacturing process, thermal management, and power density point of view. In this paper, a compact PCB-winding transformer structure is proposed to handle the medium voltage insulation by FR4 in PCB-winding. The primary side winding is built in PCB-winding and secondary side winding is still Litz wire for a lower loss. With semi-conductive shielding and stress grading layer design, the E-field can be restrained in the primary side PCB for a partial discharge free insulation. An arc section winding structure is proposed to reduce the high E-field inside the insulation layer to improve insulation performance. The layer-to-layer winding resistance and overall loss/footprint trade-off is analyzed for a low loss design. Finally, the design is demonstrated on an 800/400V, 15-kW, 200-kHz CLLC converter with 98.8% peak efficiency and 130W/in3 power density, whose transformer achieves partial discharge free up to 14.6kV.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128815013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To help accelerate a swift transition to decarbonization, alternative modes of transportation, such as electric vehicles (EV) must provide superior performance and competitive advantages in regards to reliability (longevity), efficiency (fuel economy), and volumetric energy or power density (compact integration) in contrast to fossil fuel-powered transports. However, achieving optimum designs is challenging due to the multiple physical domain interactions between thermal, electrical, and mechanical systems within an EV drivetrain. Hence, this paper focuses on the multi-parametric design analysis of the EV traction inverter system to perform trade-off studies between two competing objectives: reliability and efficiency. A seamless performance evaluation process was developed between PLECS, a simulation platform for power electronic systems and the optimization computation of genetic algorithm based on NSGA-II in Python to achieve a reliable repetition of varied operating modes of the inverter to seek optimized parameters and non-dominant solutions. A realistic, high-fidelity, and multi-domain EV model based on the known physical parameters of Nissan Leaf was developed in PLECS along with a dynamic driving profile. The paper further discusses parametric design analysis and comparison based on different power module materials and operating conditions, such as EV battery voltage and power module switching frequency. The simulation results show that an optimized SiC solution can provide a higher efficiency design whereas higher reliability can be expected with the optimized IGBT-based designs.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128866150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cascaded-magnetic-based electromagnetic energy harvesters, consisting of a clampable core and a high-permeability ungapped core, feature relatively higher density and predictability in energy harvesting. The clampable core only facilitates a non-intrusive mounting of the energy harvester onto the primary wire while the high-permeability core is the heart of the energy harvester to guarantee the maximum power extraction and usable output voltage. Therefore, reducing the clampable core size is critical to increase the power density without drastic power degradation. This article first presents the optimization conditions of the clampable core volume based on the harvested power level and other design requirements. FEM simulations using Ansys Maxwell and LTspice simulations are both executed to show the influence of the core parameters on the amount of harvested power and core saturation. This paper also presents an energy improvement method, controlling power transfer window via active switches, to improve the harvested power level. The boosted power is evaluated in this paper via experimental results.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134637202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rate of failure of a power module (PM) is directly related to operating temperature, its' variation and distribution. As a result, temperature dependent offline reliability estimation with thermal network or finite element (FEA) based analysis has received much attention in the recent past. However, these conventional approaches only estimate degradation rating based on a constant mission profile, applied load, and initial condition of the PM, which can increase estimation error due to random load profile and aging of PM material substances. Therefore, a novel thermal network model has been developed considering the aging factor for online state-of-health (SOH) monitoring. Towards this objective, an advanced loss model is developed in a non-invasive method with semiconductors' change in electro-thermal properties with temperature. The resultant heat loss is used to track junction temperature using Cauer thermal model considering PM geometry and material properties. The model is improved with online thermal characterization in healthy and degraded conditions. Subsequently, the model has been updated with cross-coupling effect between semiconductors using FEA. The developed model is validated with an electric vehicle (EV) traction inverter module.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127242617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This Paper proposes a novel converter concept that employs B6-type circuits on the input and on the output side and a low-complexity Discontinuous Conduction Mode (DCM)-type or a Dual Active Bridge (DAB)-type modulation strategy, thereby enabling single-stage isolated three-phase ac-dc power conversion with sinusoidal grid currents and controlled dc output voltage. The converter operation is detailed on the switching-frequency and on the grid-frequency time scale and verified by means of circuit simulations. The converter control characteristic and the main power component stresses are discussed and design guidelines for a 6.6 kW prototype system with an expected efficiency $eta > 98%$ are presented.

The ANPC topology is widely used as an interface for efficient power conversion in medium-high power applications. Direct MPC allows fast and decoupled control of state-variables through a user defined cost function. However, the state-variable predictions require iteration of 27 switching vectors which increases the computational burden, making the deployment of the controller infeasible to low-cost mass-marketed DSPs. The method presented in this study restricts the number of switching states being checked through a limitation criteria. The criteria reduces the number of states being checked from 27 to just 7 at maximum, making the computational burden identical to that of a six switch 2L-VSC. The presented approach is verified by deploying the controller on a TMS320F28379D DSP and the plant on PLECS RTBox 3. In addition, the presented method is compared against an existing state-of-the-art state vector limitation technique. The results show an improvement in grid current THD throughout the power range at the expense of marginal increase in switching frequency of the converter.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115051285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
