【 摘 要 】

With the development of power electronics technology, how to improve the output quality of DC power supply has become an important subject of recent scholars' research. This paper put forward a new PWM control mode, the DC power supply output ripple is effectively suppressed. The theoretical basis is given by the principle analysis. Finally, the accuracy of the theoretical analysis is verified by simulation.
