Abstract

The invention provides a power converter and method for controlling same, comprising a plurality of switch elements, an inductive reactor, and at least two ports for the movement of electrical energy. Any energy-moving port may be made unipolar, bidirectional, bipolar, or bidirectionally bipolar. Ports may be equipped with sensing circuitry to allow the converter output to be controlled responsively to an input signal. The invention may be configured to be used in many ways, for example, as a power-supply, as an amplifier, or as a frequency converter. The invention may comprise energy predictive calculating means to obtain excellent transient response to line and load variations. The invention may also include a switch to create a low impedance path around the inductor to allow current to recirculate through the inductor when it is not needed at any of the ports.
