摘要: 设计了一种DSP控制移相全桥ZVS软开关式DC/DC升压变换器。主变换电路使用了移相全桥设计,能较好地实现零电压通断,且转换效率明显提高。控制电路采用DSP处理器控制,能有效地进行实时校正,获得稳定输出,同时由于软件控制调整移相角α,可实现直流输出的宽范围调整,具有较高的工程应用价值。

Abstract: This paper designs a DSP control ZVS phase shifted full bridge soft switching DC/DC boost converter.It can better achieve zero-voltage-off and increase in conversion efficiency due to the design of main converter circuit using f a phase-shifted full-bridge.The control unit adopts the DSP processor for effective real-time correction and stable output.The software control for adjusting the phase angle alpha realizes a wide range of DC output adjustment.

Key words: phase shift control;ZVS soft switching;TMS320F2812
