摘要 |
A digital power factor correction circuit including a digital comparator that compares the actual DC bus voltage of an electric circuit with a desired DC bus voltage to produce a digital attenuation signal in the form of a pulse width modulated signal that is used to attenuate the voltage from a time-varying source. The attenuated source voltage is used as the current demand signal for a current controller that controls the current drawn from the line. <IMAGE> |
