  • Power supply apparatus and method thereof for input harmonic current suppression and output voltage regulation
    Patent number: 6665198
    Abstract: An power supply apparatus for the input harmonic current suppression, input power factor compensation, and an output voltage regulation and a method thereof is provided. The power supply apparatus electrically connected to a AC power has a first power converter electrically connected in parallel with the AC power for providing a first compensating voltage and controlling the first compensating voltage to reduce harmonic components of an input current so as to cause the input current as a substantial sinusoidal wave and in phase with the input voltage, and a second power converter electrically connected in series with an output end of the power supply apparatus for providing a second compensating voltage in order to maintain the output voltage at a desired level and waveform. The related methods are also discussed.
