Abstract

A first inverter has a set of first output phases coupled to a grid voltage source. A second inverter has a set of second output phases coupled to the grid voltage source. A phase measurement device is adapted to measure at least one reference phase of the grid voltage source at a reference phase point. An electronic data processor is configured to determine an observed phase difference between the reference phase point and an observed position sample of one of a pulse-width-modulation carrier signal of the first inverter, the second inverter, or each parallel-coupled inverter. The electronic data processor is configured to determine a target phase difference between the reference phase point and target position sample of one of the pulse-width-modulation carrier signal. The electronic data processor is configured to determine a frequency adjustment to the pulse-width-modulation carrier signal of the first inverter, the second inverter, or all parallel-coupled inverters, based on a difference between the observed phase difference and the target phase difference.
