DIGITIZED METHOD FOR GENERATING PULSE WIDTH MODULATION SIGNALS

摘要

A digitized method for generating pulse width modulation (PWM) signals is disclosed. In the digitized method, multiphase PWM signals are generated by altering the reference levels so that fully on duty cycle or fully off duty cycle of each phase PWM signal can be achieved. Therefore, the digitized PWM signal generation method in the present invention can be applied to any application apparatus having boost/buck converter.
