提出一种新的控制开关功率变换器的调制技术:双脉冲跨周期调制(dual pulse skipping modulation,DPSM)技术.不同于脉冲跨周期调制(pulse skipping modulation,PSM)技术采用单控制脉冲实现输出稳压,DPSM技术把单控制脉冲扩展为双控制脉冲,可克服PSM控制的开关功率变换器存在较大输出电压纹波的缺点.以工作在断续导电模式(discontinuous conduction mode,DCM)下的Buck变换器为例,说明DPSM技术的工作原理和控制规律.仿真和实验结果表明,有着良好瞬态性能的DPSM Buck变换器与PSMBuck变换器相比具有较低输出纹波,与脉冲序列(pulse train,PT)控制Buck变换器相比具有较宽的负载可调范围.
