Abstract :
This paper calculated and analyzed the main reasons for distortion of supply current. Then a novel control method which added an output current sampling was present. According to use the value of output current the 100 Hz ripple voltage in the output voltage was mostly eliminated, and the waveform of supply current was improved; Meanwhile the output current was feed-forward to the reference value of supply current control loop, so the dynamic performance was also improved. The theoretical analysis is verified by simulations and experiments.
