Simple PWM inverter circuit diagram using PWM chip SG3524

Here is a simple PWM dc to ac voltage inverter circuit based on IC SG 3524. The SG3524 IC chips is a fixed frequency PWM (Pulse Width Modulation) voltage regulator control circuit, with indifferent outputs for single ended or push pull applications. The SG3524 IC integrated circuit has all the functions necessary for the production of a regulating power supply, electrical inverter or switching regulator on a single chip.

Moreover it can be used as the control element for high power output purposes. We know pulse width modulation PWM theory, i.e. a method of adjusting the width of the pulses in a pulse train relative to a control signal. If greater the control voltage, wider is the resultant pulses. Using a sinusoidal frequency as the control voltage for pulse width modulator circuits, it is likely to generate a high power waveform whose average voltage varies with the sine wave, which is suitable for driving ac loads.

555 timer IC Inverter circuit schematic 12V to 220V

This article explains What is inverter? And how can you construct your own simple low cost 12V to 220V inverter circuit. An inverter is nothing but a DC to AC converter. Inverters are very useful electronics products for compensating emergency power failure, as it performs DC to AC conversion.

Simple low power Inverter Circuit (12V DC to 230V or 110V AC) diagram using CD4047 and IRFZ44 power MOSFET

This simple low power dc to ac inverter (dc to ac converter) circuit converts 12V DC to 230V or 110V AC. By doing simple modification you can also convert 6V DC to 230V AC or 110V AC. It can be used as inverters for home needs to enable light loads (electric bulb, CFL, etc) at the time of electricity failure. You can construct this circuit of simple inverter at a cheap rate with locally available components. Use a 12V rechargeable battery and battery charging circuit for this dc to ac inverter. We have already posted the circuit for battery charger.
