  • Capacitor input type rectifier having a circuit for preventing inrush current
    Patent number: 5202819
    Abstract: A capacitor input type rectifier having a circuit for preventing an inrush current uses an AC phase detector for detecting the time that an AC voltage input has the smallest phase angle and provides an output signal indicative thereof to a phase control rectifier for initiating rectification of the AC voltage to provide a rectified output to a smoothing circuit for smoothing the rectified output of the phase control rectifier.
