This invention pertains to a three-port isolated active bridge DC-DC power converter comprising a control unit, a first primary-side port, a second primary-side port, two primary-side switching elements, a blocking switch, a secondary-side port and two secondary-side switching elements. The control unit is configured to open and to close the blocking switch, for preventing and allowing power flow between a primary side and a secondary side of the power converter. 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. This invention further pertains to a three-port isolated active bridge DC-DC power converter system, a multi-port isolated active bridge DC-DC power converter, a multi-port isolated active bridge DC-DC power converter system, a solar power assembly, and a vehicle.

Scalable multi-port converter for solar electric vehicles

The invention relates to a battery management system for an electric vehicle comprising a high voltage battery, low voltage battery and a bidirectional converter. The bidirectional converter is configured to connect the high voltage battery to the low voltage battery and to generate a power flow between the high voltage battery and the low voltage battery. The bidirectional converter is further configured to monitor a first voltage associated with the high voltage battery and a second voltage associated with the low voltage battery, and to control a voltage ratio of the first voltage and the second voltage to remain in a predetermined range, by controlling the power flow between the high voltage battery and the low voltage battery.
