摘　　要：交错并联变换器的主要特点是所用的变换器共用一个输出滤波器。在效率超过90%的前提下,输入、输出电容上的电流纹波小,负载变化时的动态响应更快,处理功率的能力更强。可以通过错相驱动每个并联变换器的控制信号来实现,使得有效开关频率得到提高,交错并联Buck变换器具有抵抗输入电压和负载扰动的能力,实现输出电压稳态无静差的要求。The main feature of interleaving converter is that the converters used share one output filter. Under the precondition ofefficiency above 90%,the current ripple on input & output capacitors is small,the dynamic response is faster during load change, and ability in treating power is stronger. These can be realized by using fault phase to drive the control signals of each parallelconverter,so to make effective switching frequency increased. The interleaving Buck converter has the ability to resist the inputvoltage and load disturbance and to realize the none-static-error requirement for output voltage under steady state.
