How to make a 12v 5Amp transformerless or electronic power supply which is Switched Mode Power Supply(SMPS) based.
By: Alok kumar
Making a 12v 5A Transormerless electronic power supply is really a complicated task and if we made it the resulting circuit will become a bulky circuit. Don't worry about it, Now we are going to solve it together.
In this post, We are going to take advantage of High frequency method over a small transformer or inducuctors coupled together over a ferrite core, This method also known as Flyback Converter type design. As we all know at High frequency, we can make a small transformer conduct even much higher current or power far above the rated...
specification without damaging it. So just use this property to exploit the small transformer to get high amperage from a little ferrite transformer. Simply switch mode power supply simply the property of inductor that it always opposes the rate of change of current flowing through. So simply by switching on and off the inductor will result in boosted output across the inductor with opposit polarity. The simplest switch mode power supply (smps) are boost converter circuit but it is not a isolated power supply from mains so today we are going to make a flyback converter power supply (smps based) to get a highly regulated output by using a beedback by optocoupler to tightly regulate output and is also isolated from the mains supply also for our 12 volt 5 ampere electronic supply which is switch mode power supply ( smps based) to be stable tightly regulated and isolated like we need .
