Power Inverter Drive Application Circuit Uses a Six IGTs to Drive a 2-HP AC Motor

Power Inverter Drive Application Circuit uses six IGTs to drive a 2-HP AC motor. Sensing the dc current in the negative rail and inhibiting the gate signal protect the IGT from overload and shoot-through (simultaneous conduction) conditions. If a fault continues to exist for an appreciable period, inhibiting the switching regulator causes the inverter to shut off
