  • Patent number: 9876440
    Abstract: Disclosed herein is an active rectifier. The rectifier includes a rectifier unit, a driver unit, and a switching device control circuit unit. The rectifier unit includes first and fourth transistors configured to become conductive when the voltage of an alternating current (AC) input is negative and apply the current of the AC input to a rectifier capacitor, and second and third transistors configured to become conductive when the voltage of the AC input is positive and apply the current of the AC input to the rectifier capacitor. The driver unit outputs first to fourth drive control signals, and drives the first to fourth transistors. The switching device control circuit unit compares the first drive control signal and the second drive control signal with the AC input, and outputs switching device control signals to delay the first to fourth drive control signals based on the extents to delay.
