  • Multiple output rectifier and operation method thereof
    Patent number: 10673350
    Abstract: A multiple output rectifier includes a comparator-based active rectification circuit and a controller, wherein the controller is coupled to the comparator-based active rectification circuit. The comparator-based active rectification circuit is used for generating and outputting each output voltage of a plurality of output voltages according to an input voltage, the each output voltage, and a control signal corresponding to the each output voltage. The controller is used for generating the control signal according to the each output voltage and a reference voltage corresponding to the each output voltage.
