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 direct power AC/DC conversion apparatus employs a dual branch topology. A first branch includes a first AHB switching network configured to receive an AC grid power and produce an AC power, coupled through a series resonant impedance to a first primary winding of a transformer. The first switching network includes two bi-directional switches coupled in series where each bi-directional switch includes two switching devices coupled in series in opposite polarity. A secondary winding of the transformer is coupled through an SR switching device to an output DC power. A second branch includes a diode bridge, configured to receive the AC grid power and produce a DC power, coupled to a second AHB switching network. The second AHB switching network is coupled through a second series resonant impedance to a second primary winding of the transformer. Each of the first and second branches are operated alternately and independently.
