Direct bonded copper (DBC) is applied as the insulated thermal pad to dissipate the heat generated by the GaN dies, where ceramics is employed for the thermal pad insulation. Printed circuit board (PCB) on the top of the GaN dies integrates the auxiliary power supply, the gate drive circuits and the decoupling capacitors, which can help the parasitic inductance reduction in the gate drive loop and the power loop to reduce the overshoot voltage across gate to source and drain to source. The packaged module exhibits high-current capability (150 A), high-compactness (45*33*9.6 mm3) and excellent thermal impedance from junction to heatsink. Taking advantages of the integrated gate-drive circuit, the proposed power module has simpler interface for users compared to regular GaN HEMTs on the market, which only needs PWM signal and non-isolated power supply to drive. To verify the electrical performance and thermal performance presented above, both double pulse test (DPT) and thermal test are conducted. DPT at 450 V/150 A shows around 54 V voltage spike only, which makes the proposed module suitable for high-power EV on-board charger or motor drive inverters.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89354218","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}

A loss analysis was performed on different primary circuit structures for the converter, and a full-bridge structure was selected. In addition, a quarter-turn planar transformer structure was adopted. With the voltage conversion ratio of 8:1 unchanged, the adopted transformer required fewer primary and secondary winding turns, with lower alternating current copper losses, compared with an average transformer. The study also explored and optimized parallel arrangements of transformer windings, adopted parametric design of transformer dimensions, and determined the optimal balance between core losses and copper losses in a limited circuit area. The magnetic simulation software Ansys Maxwell was used to verify the magnetic flux distribution of the quarter-turn planar transformer. An experiment confirmed that the proposed LLC series resonant converter has a switching frequency, input voltage, output voltage, output power, power density, and peak efficiency of 1 MHz, 48 V, 6 V, 900 W, 63 W/cm3, and 98.2%, respectively.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87178865","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}

Extensive research has been done to address the drain-source voltage overshoot and oscillation issues by reducing the power loop stray inductance. To further enable higher switching frequency, the issues on the gate driver side still need to be addressed. The crosstalk phenomenon on gate-source voltage, as one of the major issues, has attracted lots of attention and can be mitigated by various approaches. In addition, when dv/dt is extremely high, the common-mode (CM) noise may deteriorate the control signals through the capacitive coupling, which still need to be addressed, considering just 1.5V voltage noise can lead to false triggering on the PWM input of digital isolators. In this work, four gate driver architectures in the existing literature are studied and compared in terms of the CM noise immunity. LT-spice small-signal models are utilized for simulation studies to compare the CM noise immunity of different gate driver designs quantitatively. The prototype of the optimal design was built and experimentally tested using a 3.3 kV SiC MOSFET to validate its CM noise immunity under the extremely high dv/dt, even beyond 240 V/ns.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86950803","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}

Meanwhile, the chip layout and design methodology fundamentally determine thermal and reliability performance. Hign-density power modules typically consist of wide-bandgap (WBG) semiconductor die, soldering materials, baseplate, and heatsink packed on a single substrate. To a great extent, the reliability of power modules depends on these material electrothermal-mechanical properties during variable operating conditions. Appropriate thermal management can reduce stress and enhance the component lifetime by controlling junction temperature. In this work, a fast, generic, and scalable transient thermal model has been developed for the PowerSynth layout synthesis tool to optimize layer material, thickness, and layer stack configurations by minimizing thermal stress due to thermal cycling. This model has shown approximately 3,489 times speed up with less than 10% mismatch compared to ANSYS simulation.

However, the move to higher voltages and their more compact packages challenge the insulation design. In particular, low-pressure working condition of the aircraft degrades gas dielectric strength, which leads to an increased risk of partial discharges. Thereby, this paper presents a comprehensive design of a gate driver for SiC-based Generator Rectifier Units (GRUs) for variable frequency airborne applications. A design method to control the peak electric field in high field strength regions was used to ensure the field strength in air and the PCB dielectric remain within an acceptable range. High bandwidth Rogowski switch-current sensor (RSCS) for short-circuit (SC) and over-current (OC) protection as well as phase current reconstruction are implemented to enhance the gate driver performance. Experiments were conducted, successfully verifying the gate driver’s performance meets all the design targets.","PeriodicalId":7050,"journal":{"name":"2021 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89755837","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}

Although traditional fundamental harmonic based analysis method is simple, when applied in wide voltage gain range applications, the analysis accuracy degrades significantly. Thus, to optimize the converter performance, the time domain modelling analysis for different LLC converters and operation modes are discussed. Then, based on the modelling results, a simulation tool based on MATLAB graphical user interface (GUI) is developed to visualize the converter operation. Compared with the commercial simulation software, the developed one holds the advantages of fast, accurate, and convenient. The designed simulation tool has the exact simulation results as the commercial simulation software, while the simulation speed is much faster than the commercial ones. In addition, there is no need for users to build the different converter topologies and measure the key circuit currents and voltages, which is much more convenient. The developed simulation tool can be used to achieve automated design with thousands of iterations, which are tedious and time-consuming for commercial software.

This paper proposes a reconfigurable fully digital average current control (DACC) technique along with a feedback voltage controller in a SIMO DC-DC converter, in which both the inductor current and output voltages are sampled using an ADC (with a time-multiplexing manner) once per switching cycle using an event-based sampling mechanism. The proposed technique offers (i) precise average current control, (ii) inherent current-loop stability without ramp compensation, (iii) high current-loop bandwidth, (iv) reduced flickering effects during mode transitions using combined current-source and voltage-source mode configurations, (v) scalability for single-channel, multichannel and multi-string LED driving. Discrete-time small-signal models are derived, and current-loop as well as closed-loop stability analysis is presented along with the controller design.
