Abstract
A control circuit for reducing electromagnetic interference is provided. The control circuit includes a periodic signal generator and a modulation controller. The periodic signal generator adjusts a modulation periodic signal generated by the periodic signal generator, according to a feedback modulation signal. The modulation controller is coupled to the periodic signal generator, for receiving the modulation periodic signal, and adjusting a frequency of the received modulation periodic signal according to a plurality of delay periods set according to a plurality of control signals, and generating the feedback modulation signal.
