摘要： The present invention relates to a DC-DC power converter which comprises a switched converter core operated in accordance with a primary control signal to supply a primary DC output current (Io) of the converter; said primary control signal exhibiting a minimum resolution, e.g. a minimum time step, leading to a corresponding minimum current step of the primary DC output current. The DC-DC power converter additionally comprises a controllable resistive path, or a controllable current source, connected between a pair of terminals selected from a group of: (the positive output terminal, the negative output terminal, the positive input terminal, the negative input terminal) and configured to add or subtract a secondary DC output current (Icon) to the primary DC output current (Io) in accordance with a secondary control signal to adjust the load current.

摘要： The present invention relates in a first aspect to a galvanically isolated power converter assembly comprising a first set of electrically interconnected resonant power inverters configured for generating respective output voltages and output currents. The galvanically isolated power converter assembly further a first positive summing node and a first negative summing node configured to combining the output voltages and output currents of the first set of resonant power inverters and a first common load circuit comprising a positive load input and a negative load input. A galvanic isolation barrier comprises first and second common isolation capacitors electrically insulating the common load circuit. Each of the first and second common isolation capacitors possesses an official safety rating.
