Description
Summary:This paper describes detail procedures of testing high voltage capacitor charger for 7 kV, 150 kJ pulsed power application. The designed high voltage capacitor charger was developed based on current source load resonant converter and its average charging power is 35 kJ/s. The various kinds of testing were performed including normal operating condition and the malfunctioning condition of the system. The tests for malfunctioning were performed for the case of open during charging, short during charging and misfiring during charging. The charging time of 150 kJ is calculated less than 7 seconds and it was experimentally confirmed that it shows very reliable operation even for the fault operating conditions of the system.
