INVERTER FOR CONTROLLER OF ELECTRIC VEHICLE

摘要

PURPOSE: An inverter for controller of the electric vehicle is provided to decrease the noise generation with a simple circuit. CONSTITUTION: An inverter(12) comprises 6 IGCT(Integrated Gate Commutated Thyristor) switching devices(12a-12c') converting DC power to 3 phase AC one, and a clamping circuit(12d) decreasing the rising ratio(di/dt) of current to protect the IGCT switching device. Each pair of the IGCT switching devices uses the clamping circuit in common. The 3 phase of AC power is provided after converting the DC power provided to each pair of IGCT switching devices through the clamping circuit.
