Active voltage regulator systems and methods

Abstract

A power conditioning unit used in an electrical system. The power conditioning unit includes a positive bus and a negative bus that are electrically connected to a direct current load to enable supplying direct current electrical power to the direct current load; and a first phase leg, which includes a first diode electrically connected to the positive bus, a first transistor electrically connected to the negative bus, and a first node between the first diode and the first transistor. The first node is electrically connected to an alternating current power source to enable the first phase leg to receive a first phase of alternating current electrical power from the alternating current power source and the first transistor opens and closes to control flow of the first phase through the first phase leg to facilitate generating the direct current electrical power at a target voltage using the alternating current electrical power.
