The digital control technology using in power electronics has becoming more and more popular. Based on the fly- back converter, this paper designed a digital control hardware circuit block diagram which can realize fast respond to the load change, and concretely designed precise power supply circuit, voltage and current isolation sampling circuit, driver circuit. Moreo- ver, due to the shortage of existing PID arithmetic acting in dynamic response, this paper analyzed a kind of integrated arithmetic based on incremental PI parameters and PWM duty compensation arithmetic which can achieve fast dynamic respons~ Software de- sign flow chart was designed, prototype was designed and finally experimental results were given.
