Abstract

A DC-DC power converter has been developed to charge power capacitors to 16 kV from a 400 V battery bank. It is designed to charge an 8.5 MJ bank nine times in 3 min. The converter is composed of six modules, each producing 12.5 A of charging current, and an enclosure which houses the modules and provides control power and a master controller. The six 200 kW modules have a combined power rating of 1.2 MW. The pulse width modulation converter system operates at 24 kHz and contains inverters with power metal-oxide-semiconductor field effect transistors (MOSFETs) as the principal inverter components, 200 kW power transformers and power inductors, and full-bridge rectifiers with fast recovery diodes. The converter modules have a volume power density of 1.0 MW/m³ and a mass power density of 1.2 kW/kg. The converter design and test results are described
