Commutation between grid and inverter [Patent WO 2025/177277 A1]

Abstract

A method of transitioning between supplying electrical power from a three phased supply to a load through three activated electrical supply pathways of a first supply module, to supplying power to the load through three activated electrical supply paths of a second supply module, including: monitoring a sector of the three phase supply; selecting a first phase for transition, based on the sector; and activating a first pathway through the second supply module, corresponding to the first phase and deactivating a first pathway through the first supply module corresponding to the first phase, while at least one pathway of the first supply module remains activated.
