The circuit converts DC supply into AC stepped up voltage. It comprises of six units. These are the Oscillator unit which produces an alternating signal for driver. The driver is a buffer IC (CD 4050) to supply the dual alternating outputs responsible for switching on and off of the power transistor, the switching unit uses six power MOSFETs to switch on and off the DC voltage to be inverted, the transformer unit which is use to couple the voltage swings due to switching of the transistors at its primary center tap to a square wave. The low battery unit is used to monitor the battery voltage, the change over unit which changes the output supply from the inverter to mains supply and finally the charging system which charges the battery. The result is an input DC voltage inverted to an AC stepped up voltage.Undergraduate Theses
