INTRODUCTION TO SIMPLE INVERTER CIRCUIT Now i am with another SIMPLE project, INVERTER. I hope you are already familiar with the term INVERTER. INVERTER is used to convert low Voltage direct current (DC) to high Voltage Alternating Current (AC). By using an inverter you can generate 230V, 50Hz power supply from a 12V battery. This circuit may very helpful to you at the time of Power Failure. ie; you can power any device, commonly works in single phase AC supply at the time of Power cut by using a battery (rechargable battery is recommended).
