How to build your own DC to AC power inverter?

Power inverter circuits (commonly referred to as power inverters) convert DC (direct current) into AC (alternating current) electrical energy. The majority of power inverters produced for the United States converts an input source of 12 volts direct current into 120 volts at the outlet of the inverter. There are a lot of power inverters which are manufactured for automobile or home use. You can also build your own using a few electronic components.

  1. You will have to get some electrical wire and cut it into 8 pieces. Remove about half an inch of the wires insulation at their ends. Solder one of the ends of your first piece of wire to one of the terminals of a 24 volt transformer on the center-tap side. The end of the second piece of wire solder on the other end terminal.
  2. Take the negative lead of a 0.47 Microfarad electrolytic capacitor and twist it together with one of the leads from an 800-ohm resistor, the collector lead from a bipolar junction transistor and the free end of your first wire. You should solder the connection.
  3. Take the positive lead of the capacitor and twist it together with your second 800-ohm resistor, the collector lead of your second transistor and the free end of your second wire. Make sure to solder that connection.
  4. Take your third piece of wire and solder one of its ends to the transformer's center-tap. Now take a battery clamp terminal and loosen its top screw. Attach to it the free end of your third wire. Tighten the screw and solder your wire to the terminal.
  5. Take one of the ends of your forth wire and twist it together with a lead from an 80-ohm resistor, a lead from another 80-ohm resistor and two collector leads from a transistor. Solder this connection. Attach the wire to the screw of the second battery clamp terminal, tighten the screw and solder the connection.
  6. Take one of the ends of your fifth wire and twist it together with the free end of your first 800-ohm resistor. Solder that connection. Take the other end of the fifth wire and twist it together with the second transistor's base lead and the free end of your first 80-ohm resistor. Don't forget to solder that connection.
  7. Take your sixth wire and twist it together with the free end of your 80-ohm resistor and with the first transistor's base lead. Solder your connection. Twist the other end of the sixth wire together with the second 800-ohm resistor's free lead and solder the wire pair.
  8. Take your seventh wire and solder one of its ends to an end terminal of the transformer on the side which lacks a center-tap. Take a ring terminal, slip it over the other end of your seventh wire and solder it. Take one of the ends of the eighth wire and solder it to the last transformer terminal. Take another ring terminal and place it over the other end of your eighth wire. Solder the wire to the terminal.
  9. Take a 12-volt battery. Connect the battery clamp which you wired to the center tap to the battery's negative terminal. The other battery clamp connect to the battery's positive terminal.
