Major Components Rectifier Converts AC input voltage to DC voltage. The rectifier uses IGBT (Insulated Gate Bipolar T ransistor) power transistors and a Pulse W idth Modulated (PWM) technique to provide input power factor correction and to minimize any harmonic reflected onto the input power lines. Inverter Converts DC voltage from the rectifier or from the batteries into AC output voltage to maintain the attached load. This module uses the IGBT technology to provide digital power quality .
