摘　　要：介绍了dsPIC30F2020芯片及其在DC/DC变换器控制中的应用,并用该芯片作为主控制芯片设计了一个平均电流模式控制的移相控制全桥DC/DC变换器,最后比较了数字式控制DC/ DC变换器与模拟电路控制的DC/DC变换器的优缺点。The chip dsPIC30f2020 is introduced and its application in DC/DC convertor is discussed. A phase-shifted zero-voltage-switching DC/DC PWM full-bridge convertor which is controlled by digital controller is developed. At last, the digital controller with traditional controller based on analogue circuit is compared and their merit and disadvantage are pointed out.
