Conventionally, they may be used to recharge a vehicle’s battery pack, but as they are connected to the grid, they can also be used to provide ancillary grid services, such as reactive power support and longer-term battery-to-grid backup. On-board chargers also represent a potentially significant portion of a vehicle’s weight and can take up considerable volume. This paper discusses the design and implementation of a high power density Level II charger converting between 400 VDC and 240 VAC, utilizing two interleaved flying-capacitor multilevel converter stages combined with a full H-bridge unfolder or active rectifier. The focus of this work is the ac-dc/dc-ac power stage, with the goal of high efficiency and power density. Thus, power factor correction (PFC) control and twice-line-frequency buffering are not discussed or implemented in this work. Experimental results show a peak system efficiency of greater than 98.9%, a power output of 7 kW, and an effective switching frequency at the inductor switch nodes of 720 kHz.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129935962","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}

Based on a medium-voltage DC (MVDC) isolated port, this configuration is proposed for applications regarding offshore wind energy conversion systems (WECSs) with high-voltage DC transmission (HVDC). As an alternative to increase the power density on offshore systems, the use of DC-DC converters to process the energy produced by the wind turbines is a modern trend in this type of configuration. This topology can be used in WECSs as the interconnection between the MVDC transmission bus and the wind turbines (WTs). The use of full-bridge modules per phase in the primary side shares the current among the semiconductors, with consequent reduced losses at high power levels. Besides, the high-frequency step-up transformer leads to reduced overall dimensions. With the use of neutral point clamped (NPC) converters connected in cascade in the secondary side, it is possible to reach obtain a MVDC output without the increase of voltage stresses on the semiconductors.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116477379","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}

Modular battery packs utilize DC/DC converters that are connected in series for high output voltage or connected in parallel for high output currents. An active battery management system (BMS) utilizes the cell state of charge (SOC) to control the cell current. The individual control to input current transfer functions vary with the number of converters in parallel. This paper presents a small-signal model for the parallel converters as a multi-input, multi-output (MIMO) system that shows the interactions among the input current transfer functions. The small-signal model is utilized to design the feedback loop. The paper uses hybrid feedforward control to reduce the interactions between the coupled input-current regulation loops; which simplifies the implementation, increases modularity, and eliminates the need for a central controller. that is generally employed in MIMO systems. The analysis is verified by simulations and by experiments. A 300 W module consisting of three parallel output 100 W boost converters for a cell active balancing management system is used for hardware validation.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128422191","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}

However, a suitable modeling framework is not readily available, considering different operating modes to study its high frequency large- and small-signal behaviour and to design the controller. This paper presents a discrete-time framework for accurate modeling of an interleaved current-fed dual active bridge DC-DC converter, particularly highlighting its large- and small-signal dynamics. The proposed framework considers the exact dynamics of individual modes, taking into account the possible power circuit parasitics, and attempts to derive a generic form of approximate second-order discrete-time models. Various discrete-time small-signal transfer functions are derived and verified with the SIMetrix/SIMPLIS simulation in the frequency domain. A pair of complex conjugate poles and zeros are found to exist in the control-to-output transfer functions near the converter natural frequency. A GaN-based 300 W hardware prototype is made to validate the proposed model experimentally, and the modulation technique is implemented using an FPGA device. Discrete-time large-signal models are validated through the experimental results. The proposed framework can be extended to other isolated and non-isolated DC-DC converters, particularly when at least one of the state variables has zero steady state average value.","PeriodicalId":142409,"journal":{"name":"2019 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115596237","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}
