Compact DC-DC Power Design in Half-Bridge IGBT Driver

Article Preview

Abstract:

The integrated half-bridge IGBT driver need compact, high efficiency and high power density isolated DC-DC power supply, a set of two magnetic cores share a high-frequency full-bridge switches are designed. A simple circuit generates four channel drive signals, without isolation, to achieve compact on-board power supply and the best combination with the integrated half-bridge IGBT driver. The key signals are simulated, and experimental results show that the power supply is simple, reliable.
