VEHICLE INVERTER CIRCUIT AND A VEHICLE INCLUDING THE SAME, CAPABLE OF PREVENTING THE DAMAGE OF AN INSULATED GATE BIPOLAR TRANSISTOR MODULE DUE TO OVER-VOLTAGES IN A SYSTEM

摘要

PURPOSE: A vehicle inverter circuit and a vehicle including the same are provided to increase rated power density and the efficiency of an inverter and a motor by using a system voltage which is higher than the internal voltage of a clamping unit.;CONSTITUTION: A switching unit(100) includes a plurality of switching elements in order to switch a direct power to an alternating current. If overshoot is generated, a variable clamping unit(200) clamps the overshoot by turning the switching unit on. The variable clamping unit stops the switching unit by turning the switching unit off if the system voltage is higher than the internal voltage of the clamping unit.;COPYRIGHT KIPO 2010
