Abstract

Provided are improvements for systems and methods of alternating current (AC) to direct current (DC) power regulation. The system improvements include a regulation circuit having a microprocessor that controls a silicon controlled rectifier circuit. Method improvements include one or more of SCR load sharing, adaptive voltage droop compensation, and/or voltage rebound compensation.

Claims (9)

1. A multi-phase voltage regulator comprising:

a plurality of alternating current inputs;

a plurality of silicon controlled rectifiers, each silicon controlled rectifier being electrically coupled to one of the plurality of alternating current inputs; and

a microprocessor including:

a battery voltage input; and

a plurality of phase inputs, wherein the plurality of phase inputs is at least equal in number as the plurality of alternating current inputs,

wherein the microprocessor is configured to sense alternating current electronic signals received through the phase inputs and to sense a voltage level signal received through the battery voltage input,

wherein the microprocessor is configured to compare the voltage level signal to a predetermined voltage reference level, and

further wherein the microprocessor is configured to activate and deactivate all of the plurality of silicon controlled rectifiers, where each activation occurs only when the voltage level signal is below the predetermined voltage reference level, and each activation is substantially synchronized to a predetermined state of a different alternating current electronic signal than an immediately preceding activation.
