Function

• An inverter is an electronic device that transforms the type of electric power that car batteries use--DC power--into the sort that household electrical devices use, AC power.
  
  

Parts

• You can build your own inverter circuit with a simple transformer, four resistors, two capacitors, two diodes and two transistors.
  
  

Capacities

• This simple homemade circuit is capable of supplying enough power to run televisions, computers, stereos, DVD players and even fans.
  
  

Considerations

• A simple inverter circuit such as the one described here is not capable of powering high-wattage devices like coffeemakers and portable heaters.
  
  

Warning

• Be careful when handling this homemade circuit. It will draw dangerous levels of current from the car battery. Do not touch any part of the circuit while it is in operation.
