    how to hold the pwm power voltage stable?

    The pwm power is a part of my project.Now ,I have a problem:how to hold the pwm power voltage stable? My method as a feedback control:

    first: down the voltage (pwm power stabler voltage 310V)
    second: use a A/D sample the low voltage,transfer the result to DSP,then
    the DSP adjust the pwm's the proportion between high level and low level to make power voltage up or down.


    Thank you!
