How to make a 0-300V Variable Voltage, Current Transformerless Electronic Power Supply or Driver Circuit.

How to make a 0~300v Variable Voltage & Current Transformerless Electronic Power Supply or LED Driver or Electronic Dimmer.

In this post i am going to show how to make a variable transformerless electronic Power supply or Electronic Dimmer means this power supply can vary  both voltage as well as current. This circuit can be of great importance like checking different appliances (samll as well as big appliances) without worrying about buying their power supply which is diffrent for different appliances. It can be used on any device....

One day when i was testing a led strip on  Electrical Dimmer or Auto-transformer ( which actually is a bulky circuit), due to its bulkiness i start thinking why not develop a Transformerless Electronic dimmer for ease of use. So i come up with this circuit.

I made this circuit, short circuit proof. so enjoy making this marvel piece of Gadget.
