Design and Implement of Low Ripple and Quasi-digital Power Supply

摘要：

A switch linearity hybrid power supply based on single chip microcomputer is designed which merged the merits of the switching and linear power supply.Main circuit includes pre-regulator which works in switching mode and series regulator which works in linear mode.Two-stage regulation mode was adopted in the main circuit of the power.A single chip computer (SCM) and high resolution of series D/A and AJD converters are applied to control and measurement which achieved continuous adjustable and low ripple constant current or voltage power supply.

关键词： low-ripple quasi-digital phase shift control linear power supply
