Design of High Light-load Efficiency Two Stage Bidirectional 800V-14V Converter
This article proposes an 800 to 14 V bidirectional DC-DC converter architecture for Electric Vehicle (EV) applications. This architecture is conducive to have high efficiency at light loads and miniaturized size by means of using low-voltage power electronic devices and a new integrated magnetic design. The prototype achieves an efficiency of 93.5% at 10% load and a peak efficiency of 95%, with a power density of 9.18 kW/L.
