A system and method of use of a three-phase inverter driver includes three single-phase inverters that are connected to the three-phase AC input of electric vehicle supply equipment (EVSE) so that each of the single-phase inverters provide one of the three phases of the AC signal used by the EVSE. The single-phase inverters are rectified and either have variance in their output frequencies or have their phases staggered so that the maximum voltage provided to the EVSE remains at a consistently high level. In some cases, the three phases each cross polarity simultaneously, resulting in a drop in the maximum three-phase voltage, so low-capacity capacitors are used in conjunction with the inverters to bridge these gaps in voltage. These systems and methods use readily available, inexpensive components that have regulatory safety-approval and therefore may allow implementation on a vehicle or with a load leveling energy storage system.
