DAB Converter for EV Onboard Chargers Using Bare-Die SiC MOSFETs and Leakage-Integrated Planar Transformer

Yongwan Park et al.

Summary: This article discusses electrical design optimization of a 3.3 kW, 380 V to 250-380 V, 500 kHz, dual-active-bridge dc-dc converter for onboard chargers, operated with constant-power (CP) charging. It employs a low-parasitics, PCB-based, wire-bondless full-bridge module featuring SiC MOSFETs and compact coolers, operating at high switching frequency for improved power density and efficiency. Experimental validation shows operation with ZVS over the entire charging profile and a peak efficiency of 98%.

An Enhanced Dual Active Bridge Converter With Full Domain ZVS by Utilizing a Simple Segment Control for Wide Voltage Range Applications

Deliang Chen et al.

Summary: This article introduces a dual-transformer-based enhanced dual active bridge (DAB) dc-dc converter for wide voltage range applications. By splitting the power leg and transformer of the conventional DAB converter (CDABC) into two parts, it increases the control freedom and wide voltage operating range. The article also presents a simple segment control strategy with four control degrees of freedom to reduce conduction losses and switching losses and avoid inrush from mode switching.
