This paper presents the design and implementation of parallel connected 400 Hz frequency converters that supply power to military equipment. Achieving tight steady-state and transient voltage regulations and high efficiency in inverters with high fundamental frequency presents great challenge both on the control system design and the power stage design. This study develops and implements a controller with paralleling functions that achieves the stringent power quality requirements. It also includes developing the circuit models of the controller and the converter stage, and finding the optimum design based on the simulation results. Then, experimental work is performed on the converters built at the rated power to validate the design. Finally, the test results demonstrate that the developed control system and the converter design achieve the desired specifications demanded by the military applications.
