SCALABLE MULTI-PORT CONVERTER FOR SOLAR ELECTRIC VEHICLES

An isolated active bridge DC-DC power converter comprising a primary side, a secondary side, and a control unit. The primary side comprises one or more input power ports, a low voltage port, two primary-side switching elements for each of the one or more input power ports, a primary-side converter inductance for each of the one or more input power ports, and a primary-side transformer winding for each of the one or more input power ports. Each pair of primary-side switching elements and a respective primary-side converter inductance is arranged to form a half-bridge arrangement for bidirectionally converting power between a respective input power port and the low voltage port. The secondary side comprises a high voltage port, two secondary-side switching elements, and a secondary-side transformer winding magnetically coupled to the primary-side transformer winding. The control unit is configured to control the two primary-side switching elements and the two secondary-side switching elements for converting power between the primary-side ports and the secondary-side port.
