Abstract

See full text

To provide current balancing between paralleled first and second inverter units of a modular converter system, a system controller is configured to determine a gate driver offset value based on respective voltages at the phase output nodes of the first and second inverter units. The system controller controls gate drivers for the first and second inverter units based on the determined gate driver offset value. In turn, the gate drivers drive the first and second inverter units with subsequent drive signals such that the amounts of current provided by the first and second inverter units when producing an in-phase power output are balanced.
