摘要:

针对半桥IGBT集成驱动板上隔离电源及驱动板负载的特点,设计了一种两组磁芯共用一组高频全桥开关的DC-DC隔离电源。简洁的电路产生4路全桥驱动脉冲信号,无需隔离,实现了板上电源的紧凑设计,提高了功率密度。对关键信号的产生进行了仿真实验,结果表明,该电源电路简洁、高效、可靠,与IGBT半桥集成驱动板达到了良好的结合。

关键词: 半桥驱动, IGBT, DC-DC, 紧凑设计

Abstract:

The integrated half bridge IGBT driver requires compact,high efficiency and high power density isolated DC-DC power supply.In this paper,a set of two magnetic cores share a high-frequency full-bridge switches is 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 and reliable.

Key words: half-bridge driver;IGBT;DC-DC;compact design
