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

Hey, in this article we are going to see the circuit diagram of a 230V/12V, 1A SMPS. It basically, converts 230V AC supply into 12V DC supply. SMPS means Switched Mode Power Supply. SMPS power supplies are very power efficient, compact in design, and lightweight. The other way to convert 230V AC into 12V DC is by connecting a rectifier circuit with a step-down transformer. But this arrangement is very less power efficient and heavy in weight due to the big transformer size. Nowadays, the use…

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

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.

Here is 12V/13.8V high current power supply circuit, 5A,10A,15A,20A,25A, and 30A. For using Radio transmitters in-home, Using normal parts.

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

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 high power adjustable switching power supply is perfect for the purpose of laboratory work. The topology used to design the system is switching topology – half controlled bridge. Written […]
