A Design Method Of Research Based On Switched Networks Applied To DC-DC Converter

Switch power source is the voltage regulation source that revision power switch is working by switch fashion. The core part of switch power is a DC converter, changing the DC- voltage into all kinds of DC- voltage that are different polarity and value. As the conformation of switch capacitor Converter doesn't contain magnetic elements, volume and weight can reduce further. Fitting for chips integration, it is supplied a good achieved way for power supply of small size or portable devices. This paper expounds a way of common topology and control method in switch capacitor DC-DC converter, makes a commentary on common analysis method, discusses on efficiency and the appliance in traditional switch. Propose a new topology conformation of switch capacitor DC-DC converter, expounds its theory in detail, analyzes its steady state by status space average method, and simulates by PWM control. Tests and verifies the theory validity.
