Abstract

A new full digital control method has been proposed. This method employed an advanced main circuit topology combining with an ARM MCU. Using the state space averaging method and following the method deriving the small-signal model of Buck converter, the small-signal characteristics model of DC/DC converter can be derived. Using no steady error quadratic optimal control method, the problem of PID parameters is transformed into solving optimal feedback coefficient matrix, the digital controller of full-bridge DC/DC converter can adjust the parameters online. The power supply can realize leading leg's ZVS and lagging leg's ZCS in a big load range. The whole system has concise hardware structure, reliable control method and good man-machine interface, so it has high practical value.
