Abstract
A DC-DC converter includes a first port at a primary side of a transformer including a primary-side converter with primary-side switches and a second port at a secondary side including a second port converter with second-port switches and a resonant circuit including a first inductor, a capacitor, and a second inductor in LCL-T arrangement. A third port at the secondary side includes a third port converter with third-port switches. A controller controls the primary-side switches, the second-port switches, and the third-port switches at fixed-frequency for operation in a first mode, in which the first port supplies power to the second port and the third port, in a second mode, in which the second port supplies power to the first port and the third port, or in a third mode, in which the second port supplies power to the third port while the first port is disconnected.
