Abstract: A voltage control method for a power converter includes: acquiring a current of a first primary side winding of a transformer circuit of the power converter; integrating the acquired current to obtain an average voltage; comparing the average voltage with a reflected voltage associated with a current of a secondary side winding of the transformer circuit; and adjusting a duty cycle of a switch of the power converter based on an obtained comparison result for adjustment of an output voltage of the power converter.
