Webinverters. The high-side and a low-side IGBT switch of the half-bridge are used to apply positive and negative high-voltage DC pulses, respectively, to the motor coils in an alternating mode. A single, isolated gate driver IC drives the gate of each IGBT and galvanically isolates the high-voltage output from the low-voltage control inputs. WebSwitching Characteristics of IGBT As the IGBT is a voltage-controlled device it only requires a small voltage for the gate to remain in a conduction state. IGBT are unidirectional devices that only switch current in the forward direction, which is from the collector to the emitter.
