Inverter circuit in this article is the inverter circuit 12 volt DC to AC 220 volts, which uses a transformer without CT. As the power switching circuit inverter, DC to AC inverter circuit uses a MOSFET power transistor types. This inverter circuit can be used for 220v lights with a voltage source 12 volt battery or accumulator. Output voltage DC to AC inverter circuit as shown below is a series of square wave AC voltage, so it can be used to power a 220V incandescent lamps as well. Complete the scheme and a list of DC to AC inverter component, can be seen in the following figure.
12V DC to 220V AC Inverter With MOSFET
From DC to AC inverter circuit with a MOSFET above, there are several components that serve as a TTL square wave generator. Working frequency range DC to AC inverter above were determined by the oscillator circuit, and the operating frequency range can be set or adjusted using the variable resistor VR1.
Output voltage DC to AC inverter circuit above were determined by the transformer primary terminals are used, the above circuit voltage DC to AC inverter output can be selected between 220 volts and 110 volts. Selection of output voltage inverter circuit just choose a transformer primary terminal being used.
DC to AC inverter circuit with a MOSFET as shown in the picture above is pretty simple and can be made with PCBs matrix (hole PCB) for IC. Layout and wiring path from DC to AC inverter circuit MOSFET in the circuit above can be arranged and assembled as shown below.
