12 VDC to 240 VAC Inverter

DC to AC Inverter 300x144 12 VDC to 240 VAC Inverter

This 12 VDC to 240 VAC Inverter circuit are not using special components such as the torodial transformer found in many inverters circuit. Inexpensive and components are easy to find.

Essentially, it is a power amplifier driven by an astable multivibrator. The frequency is around 1200 Hz which most 50/60 Hz-power transformers handle well without too much loss. Increasing the value of capacitors C1 and C2 will lower the frequency if any trouble is experienced. However, rectifier filtering capacitors required are considerably smaller at the higher operating frequency. The two 2N3055 transistor should be mounted on an adequately sized heatsink. The transformer should be rated according to the amount of output power required allowing for conversion efficiency of approximately 60%.

12 VDC to 240 VAC Inverter Parts list :

R1, R2 : 15 K
R3, R4 : 220 ohm
C1, C2 : 0.047uF/50 V
Q1, Q2 : 2N3638A
Q3, Q4 : 2N3055
A power inverter is a device that converts DC (Direct Current) power into AC (Alternating Current) power. The AC output is usually 120 VAC, 60 Hz (USA domestic power) or 230 VAC, 50 Hz (International power). Inverters are usually used to supply AC power from DC sources such as solar panels or batteries

  1. Dear Sir

    Can you give me informayion on how to design sine wave power inverter like 12 volts input to 230 output voltage,2000 watts to 10000 watts loads on what parts electronic devices should be choose or change to have a higher output wattage so that it can be used at home and commercial appliances.If you have a ready schematic diagram much better.

    Thank you.

  2. hi sir
    if you dont mind can you give me the design of each components used in the 100W in verter circuit with IC CD4047. we did the cicuit using the circuit you posted but we need the design.if would be pleasure if you would send your contact no . kindly help us out its really urgent
