Abstract: A control method for a hybrid three-port DC-DC power converter combining a dual active bridge converter and a dual active bridge series resonant converter topology. The controller includes a first control loop to regulate power flow between the first port and the second port and a second control loop to regulate power flow between the second port and the third port. The first control loop employs a three-mode control methodology to regulate power flow through the dual active bridge converter between the first port and the second port. The second control loop is configured with a lower bandwidth than the first control loop and regulates power flow through the dual active bridge series resonant converter between the second port and the third port.

Abstract: A resonant AC/DC converter. An input end of a half bridge rectifier circuit is connected to an alternating current power supply. A clamping surge protection circuit is connected to the half bridge rectifier circuit in parallel, and is connected to a resonant capacitor in a resonant DC/DC conversion circuit in parallel. When a voltage of the alternating current power supply is greater than a voltage of a bus capacitor, the clamping surge protection circuit is configured to prevent a surge signal entering the resonant DC/DC conversion circuit. When the voltage of the alternating current power supply is less than or equal to a voltage of a direct current bus, a voltage of the resonant capacitor is clamped. The resonant DC/DC conversion circuit performs electric energy conversion on the pulsating direct current that is output by the half bridge rectifier circuit, and then performs output.
