    摘要： A power converter includes a wave generator, a low pass filter, a first control circuit, and a second control circuit. The wave generator receives an input voltage, and converts the input signal into a wave signal according to a first control signal and a second control signal. The low pass filter filters the wave signal to generate an output voltage. The first control circuit generates the first control signal according to the wave signal and the output voltage. The second control circuit generates the second control signal according to the wave signal and the output voltage.
