  • Delay control for a power rectifier
    Patent number: 10164548
    Abstract: A power rectifier rectifies alternating electric current by using a controller in the power rectifier to control a first delay circuit in the power rectifier to turn on a high side switch in the power rectifier, wherein the high side switch provides a path for power from an input voltage line of the power rectifier to an output voltage line of the power rectifier. The controller controls a second delay circuit in the power rectifier to maintain the high side switch in an on state to change a switching state of the high side switch based on detection, by a current inversion detector, of a current inversion associated with the input and output voltage lines of the power rectifier.

  • Power Rectifier
    Publication number: 20170012553
    Abstract: A power rectifier rectifies alternating electric current by using a controller in the power rectifier to control a first delay corresponding to a first delay circuit in the power rectifier to turn on a high side switch in the power rectifier, wherein the high side switch provides a path for power from an input voltage line of the power rectifier to an output voltage line of the power rectifier. The controller controls a second delay corresponding to a second delay circuit in the power rectifier to maintain the high side switch in an on state so as to change a switching state of the high side switch based on detection, by a current inversion detector, of a current inversion associated with the input and output voltage lines of the power rectifier.
