Single Phase MOSFET Bridge Inverter Using PWM Technique

The Single Phase MOSFET Bridge Inverter Using PWM Technique is designed for studying single-phase inverter operation and pulse width modulation techniques. It provides a practical platform for understanding MOSFET switching, PWM pulse generation, frequency control, and DC-to-AC power conversion. The trainer includes protection features, a PWM pulse generator circuit, frequency control through a potentiometer, and a bulb load for practical demonstrations. The unit is housed in a metal cabinet with a clearly printed insulated circuit board for convenient operation. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
