Space State Average Model of PSM in Boost Converter
Boost变换器跨周期调制(PSM)的状态空间平均模型

Based on boost converter, a new mode named PSM is modeled and analyzed using space state average method. Some useful formulae such as output voltage ratio, relationship between modulation factor and load, conversion efficiency are given in this paper. The conclusion can be easily got that PSM is an available control mode with high efficiency, especially for converter with light loads. The simulation results are given by designing the control circuit with PSM characteristic.
