POWER-CONVERSION ENGINE

摘要

The disclosure 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 disclosure may be configured to be used in many ways, for example, as a power-supply, as an amplifier, or as a frequency converter. The disclosure may comprise energy predictive calculating means to obtain excellent transient response to line and load variations. The disclosure 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.

1. A switched mode power converter comprising:
at least two power-moving ports; an inductive reactor; a plurality of switches for connecting the ports to the inductive reactor; a reference signal; a feedback signal responsive to the voltage or current of a port; an inductive energy signal responsive to inductive energy; computation circuitry responsive to the feedback signal and the inductive energy signal for generating a predicted pedestal signal; and control circuitry for commutating the switches, said control circuitry responsive to the feedback signal and to the predicted pedestal signal; wherein the voltage or current at a port is maintained in a desired mathematical relationship with the reference signal.
