Self-protection type invertor for electric vehicle

摘要

The present invention prevents two or more switching elements, which are elements constituting the inverter of an electric vehicle, from being turned on at the same time as a unit of a pair, thereby preventing the simultaneous ON operation of the two switching elements. The present invention relates to a self-protection type inverter of an electric vehicle that can fundamentally prevent abnormalities or failures of a corresponding switching element and an inverter and a decrease in stability of the corresponding battery pack and electric vehicle caused by this, and the present invention relates to a self-protection of an electric vehicle. In the inverter of an electric vehicle including at least one pair of switching elements, the type inverter includes an element protection unit for preventing a pair or two switching elements of each pair from simultaneously ON operation, wherein the The switching element is an insulated gate bipolar transistor (IGBT), and the element protection unit may be a configuration of an inter-lock type protection circuit.
