This project present the development of a inverter power supply. The developed inverter is more efficiency and loss power is lost in the transformer than general inverter. Using high frequency modulator. The inverter with a ferrite-core transformer has ability to use high frequency. Less power is lost when compared to a steel-core transformer inverter. The signal form pulse width modulator would be to control power mosfet. Every power mosfet would be switch with high frequency. It is controlled by pulse width modulation circuit , which generates 50 Hz square wave as switching signal for inverter circuit. This type of inverter is Push-Pull inverter which work in off-line mode Finally, low pass filter circuit would be used to filter Signal 50 Hz. The outcome is AC line(220 Volt )
