Abstract
A high frequency, voltage feedback control mode power converter having a microprocessor outputs a control clock signal and a simulated output voltage to control the dead-time value of a PWM controller. The control clock signal is decided by an input interrupt process program and an output interrupt process program written in the microprocessor. By appropriately providing the control clock signal for controlling the dead-time value of the PWM controller, the efficiency of the high frequency, voltage feedback control mode power converter is raised and an output steady response is also improved.
