Abstract

See full text

A control method of a power converter for modulating a power signal outputted from a power converter to a load according to a feedback signal of the load includes the steps of: receiving a reference signal to determine outputting a modulation signal; receiving the modulation signal to determine outputting an electric conduction signal based on the working condition of a transformer unit in the power converter; receiving the electric conduction signal to determine outputting an oscillation signal of the transformer unit; modulating the duty cycle and frequency of the modulation signal simultaneously according to a feedback signal, if said feedback signal is inputted; receiving the modulation signal to change a power operating time interval for outputting the electric conduction signal; and receiving the electric conduction signal after the power operating time interval is changed to determine outputting the oscillation signal of the transformer unit.
