MAKE OWN AUTOMATIC INVERTER/UPS AT HOME EASY

Today in this tutorial will make power inverter that convert 12v dc or 24v dc to 230v AC. this circuit is handy when there is main power failure .

MATERIALS: IRF3205 OR (IRF540N, IRFZ44)

                         Two heat sinks

                         4 pieces 330 ohms resistors 5w

                         Transformer (12-0-12 to 230v)

                         DC lead acid battery

                         PCB

CIRCUIT DIAGRAM:  make your connections as under,

                    the IRF3205 FET has three terminals one is SOURCE 2nd is GATE and the 3rd one is DRAIN nominated as S,D and G in the diagram.

INPUT VOLATGE: 12VOLT DC OR 24VOLT DC

OUTPUT VOLTAGE: 230VOLT AC (SQUARE WAVE)

POWER: the power of the inverter depends upon the TRANSISTOR and TRANSFORMER.

  For more power connect many transistors in parallel and choose high power transformer.

AUTOMATIC SWITCH INVERTER/MAIN: The purpose of this circuit is when the mian AC comes from WAPDA(pakistan) or any other source the load will automatically turns on with it but when the main power fails the circit will automatically start inverter without any delay.

for this we use simple DPDT relay as shown below.
