Transformerless Power Supply (220V AC to 14V DC) circuit + pcb

Variable Power Supply 0-30V_10A using dual 2N3055 transistors, LM317, BD139, A/V Meter and two Potentiometers to control amperes & volts.

I am pretty new to SMPS circuits. I understand there's a bleeder resistor, a flyback diode circuit to power the transistorized osc circuit. I guess that the current around the MOSFET will be like a...

The 12v Transformerless Power Supply is alternative to series resistor for voltage dropping, utilizing series capacitor and bridge rectifier.

A simple variable power supply using a very few components, is an easy to build and cheap solution for electronic hobbyists and beginners.

Build a Bench top lab power supply that is capable of delivering 0 to 50 volts and 0 to 5 amp or A to the load. This electronic project can serve as a your lab power supply to test and power your experiments. With the variable supply feature, it is easy to control and deliver voltage and current to the load.

In this post I have explained 4 easy to build, compact simple transformerless power supply circuits. All the circuits presented here are built using capacitive reactance theory for stepping down

Variable Voltage Power Supply Circuit using the LM317T voltage regulator to produce a 1.5A adjustable voltage power supply from 3 to 30 volts

This adjustable power supply is capable of delivering a maximum output of 12 A with an adjustable voltage from 4 V to 20 V through many LM317 ICs connected in […] The post 12 Amp Power Supply Circuit using Parallel LM317 ICs appeared first on Homemade Circuit Projects.
