摘要： A digital power factor correction device is provided, which is an all-digital control module. The digital power factor correction device includes a voltage loop control unit, an input power control unit, a current loop control unit, and a pulse width modulation generation unit, to perform power factor correction for minimizing the phase difference between input current and input voltage through adjusting input current with an external driver and a switch unit. The voltage loop control unit and the current loop control unit contain proportion-integral-differentiation controller to form voltage control loop and current control loop, respectively. The input power control unit adjusts current waveform according to the input power, while the pulse width modulation generation unit decides stop time of pulse width modulation to produce a pulse width modulation signal, to control the external driver and the switch unit for eliminating loading effect.

摘要： A PWM step wave and sine wave driving device is provided. The driving device includes an ADC unit, an input processing unit, a first pulse width calculation unit, a register unit, a first output unit, a zero point detecting unit, a second pulse width calculation unit, a second output unit, and a multiplexer output unit. The driving device receives input signals, and output desired step wave or sine wave driving signals for driving an external electric device. The driving device detects a point of zero voltage of the system power supply by the zero point detecting unit. When the system power supply is abnormal, the first output unit outputs predetermined PWM step wave output signals, or the second output unit outputs predetermined PWM sine wave output signals. In such a way, the external electric device can be maintained for regular operation, so that the malfunction or breakdown thereof is prevented.
