In this post I will explain a very basic 12V to 220V AC inverter design using IC 555 as the oscillator stage, for generating a 50Hz frequency to the MOSFET driver stage of the inverter. We have used a center tap transformer for this design which effectively converter the battery 12V into 220V AC 50 […]

Simple 85V–265V AC to 12V 5A SMPS Design Using UC3843 (With Calculations)
In this article we are going to see a simple SMPS circuit diagram which is using UC3843 IC. This circuit can convert 85V AC to 285V AC input into stable 12V DC output. UC3843 is very popular current mode PWM controller IC used in many power supply circuits. Below we will discuss full working and […]
220V AC to 12V DC Flyback SMPS Circuit using IC 555 (7555)
This practical flyback SMPS circuit uses ICM7555 as the main oscillator, and yep the whole idea is to take 220V AC mains directly then convert it into isolated low voltage DC through a ferrite transformer.. Unlike many PWM controller designs, here we have very few parts but still it gives mains isolation, voltage feedback, current […]
IC LM7912, -12V Negative Voltage Regulator Explained
In this post we are going to learn about one super old but gold IC called LM7912 or simply IC 7912. This one is not positive regulator like 7805 or 7812, but it is negative regulator which means it gives -12V output and not +12V. If you are making op-amp circuits or dual power supply […]
Make this 220V to 12V SMPS Using UC2842 IC
This UC2842 IC based SMPS design is simple, cheap and efficient kind of isolated power supply. We can use it in off-line stuff like AC-DC adapters, battery chargers and all those small power supplies. What is cool? It takes that high voltage AC then steps it down and then keeps input and output fully isolated […]
