This application note has clearly identified some of the critical operating modes of bi-directional DC-DC converter where special design attention is needed from the half-bridge gate driver perspective. This paper has made very clear recommendation regarding boot-strap bias circuit design, including bootstrap diode and bootstrap capacitor. These guidelines and recommendation shall help many design engineers to build robust, efficient, and reliable bi-directional DC-DC converters for many automotive and industrial applications.
