Abstract:
A regulated partial power controlled converter is presented, with the partial power controlled converter containing a DC/DC converter receiving an input signal. The regulated partial power converter providing a first converted signal from a first terminal, and providing a second converted signal from a second terminal. The regulated partial power converter also contains a first capacitor connected between an output node and an intermediate node, a second capacitor connected between the intermediate node and a ground, and a charge balance circuit connected to the output node, the intermediate node, and the ground. An output power of the partial power controlled converter is based on a first partial power provided by the DC/DC converter and a second partial power provided by a charge balance circuit.
