12VDC to 230VAC 60W Inverter Circuit


Posted on Feb 6, 2014

The following circuit is a cheap completely transistorised inverter circuit ideal for driving medium loads with the order of 40 to 60 watts working with battery of 12V, 15 Ah or larger power capacity. Transistors T1 and T2 (BC548) make a 50Hz multivibrator. For having right frequency, the values of resistors R3 and R4 might need to be modified aft

er testing. The complementary outputs from Collectors of transistors T1 and T2 are provided to PNP darlington driver phases created by transistor pairs T3-T4 and T6-T7 (utilising transistors BD140 and 2N6107). The outputs from the drivers are fed to transistors T5 and T8 (2N3055) connected for push-pull operation. Somewhat bigger wattage can be accomplished by growing the drive to 2N3055 transistors (by lowering the value of resistors R7 and R8 while raising their wattage). Suitable heatsinks may be applied for the output stage transistors to keep the transistor from overheating. Transformer X1 is really a 230V primary to 9V-0-9V, 10A secondary used in reverse.
