Q:

How do you build a power inverter?

A:

Quick Answer

To build a power inverter, connect seven wires to a transformer, capacitor and transistor. Use a 12-volt DC power supply to operate the inverter.

Full Answer

  1. First wire
  2. Solder one end to the first transformer terminal. Then solder the other end to the positive lead on the capacitor, the transistor's terminal and an 820 ohm resistor.

  3. Second wire
  4. Solder one end to the free lead of the first 820 ohm resistor. Solder the other end jointly to the first 82 Ohm resistor and the second transistor's base connection.

  5. Third wire
  6. Solder one end jointly to the free lead on the first 82 ohm resistor, a lead on the second 82 Ohm resistor and the emitter connections of both of the transistors. Solder the other end to the terminals on the switch.

  7. Fourth wire
  8. Solder one end jointly to the base connection of the first transistor and the free lead on the second 82 ohm resistor. Solder the other end to the second 820 ohm resistor.

  9. Fifth wire
  10. Solder one end jointly to the capacitor's negative lead, the free lead on the 820 ohm resistor and the second transistor's collector lead. Solder the other end to the second terminal on the transistor's center-tapped side.

  11. Sixth wire
  12. Solder a ring terminal to one end and solder the other end to the switch's free terminal. Turn off the switch.

  13. Seventh wire
  14. Solder a ring terminal to one end and solder the other end to the transformer's center tap.

  15. Power
  16. Connect the positive terminal of a 12-volt DC power supply to the ring terminal connected to the switch and the negative terminal to the ring terminal connected to the center tap.
