100kV/2A three-phase constant-current repetitive-rate charging equipment
A 100kV/2A three phase constant current repetitive rate charging equipment was designed and constructed. A three phase L C converter is adopted as constant current power source. Six Insulated Gate Bipolar Transistors(IGBTs) are connected in parallel to control the stop of charge. A Programmable Logical Controller(PLC) is the central element of the control unit. The equipment is used in the repetitive rate discharge features test of the switch. It works stably under the conditions of 2A charging current, 10Hz operating voltage, 100kV repetitiverate and 1μF capacitor.
