Abstract
An active rectifier bridge circuit and an on-chip integrated system. The active rectifier bridge circuit includes: a bias module, configured to provide a first bias current source, a second bias current source, and an internal power supply for a gate driver module; the gate driver module controlled by the first bias current source, the second bias current source, and the internal power supply, and configured to process one group of alternating current input voltages to generate two groups of control signals that are mutually inverted, to generate four gate drive signals; a power switch tube rectification module, connected to the bias module and the gate driver module, configured to: perform a turn-on or turn-off operation on corresponding power switch tubes under the control of the four gate drive signals, and convert the one group of alternating current input voltages into a direct current output voltage for output.
