How to make inverter using SG3525 ic

How to make inverter easily at home. In this article, I am going to explain the power inverter project that you can use your home appliance easily. This circuit is based on the PWM IC of SG 3525.

How to make inverter – requirements

To make an inverter you need main 3 setups, that are

Battery
Inverter driver board
Transformer

Battery– use 12 v high power battery

50hz driver board – the inverter board will generate the pulses 0f 50hz and that will transfer to the transformer primary coil.

Transformer – use 12-0-12 10 a step up transformer

The PWM IC is most commonly used in the power-ups circuit and also in the SMPS circuits.

The working voltage of this circuit is 12-volt dc and you can achieve up to 1500 words according to your Transformer and the most that you are using in the driver board.

Connection and working

The driver board that producing PWM signals in pin no 11 and pin number 14. the signal producing at the frequency of 50 Hz. and the frequency has to be amplified by the power MOSFETs of the P55n06 N channel. then the drain pins are connected to the transformer. when the power is on the 50hz signal that passes to the primary winding of the coil and the transformer will producing the emf Know how to works the transformer. then inducing a voltage in the secondary coil and ( step-up transformer number of the coil is high ) so we get 220v ac.
