The ABB NGDR-03C is a high-performance gate driver unit designed to efficiently control and protect high-power Insulated-Gate Bipolar Transistors (IGBTs). This unit serves as a critical interface between the low-voltage control logic and the high-power IGBT module, providing essential galvanic isolation, signal amplification, and robust protection. It features integrated short-circuit (Vce-desaturation) detection and under-voltage lockout (UVLO) to ensure the safe operation and longevity of the power semiconductor. Commonly utilized in demanding industrial applications, the NGDR-03C is a key component in ABB’s ACS600 series frequency converters, guaranteeing reliable performance in motor control and power conversion systems.
