Simple Inverter Circuit

Construction Procedure

This simple mini inverter circuit can be completed through the following easy steps:

Cut two sheets of aluminum of 6/4 inches each.

Bend one end of the sheet as shown in the diagram. Drill appropriate sized holes on to the bends so that it can be clamped firmly to the metal cabinet.

Also drill holes for fitting of the power transistors. The holes are 3mm in diameter, TO-3 type of package size.

Fix the transistors tightly on to the heatsinks with the help of nuts and bolts.

Connect the resistors in a cross-coupled manner directly to the leads of the transistors as per the circuit diagram.

Now join the heatsink, transistor, resistor assembly to the secondary winding of the transformer.
