Abstract :
Conventional switched capacitor power convertors are unsuitable for many practical applications because of their large component count. A new modified topology is proposed for step-down DC/DC switched capacitor power convertors using a multistage structure of switches and capacitors. The component count can be reduced by up to one third or more for various designs. The ripple output and inrush current also are reduced. Simulation results and their analysis are provided
