0 50v Dc Power Supply Circuit

I make the variable switch mode power supply 0 50v 5a by tl494 mj15004 but there is a problem the power supply output never be 0v minimum output voltage never go under the 2 955v i need the power start from 0v to 50v.

0 50v dc power supply circuit. The idea was requested by mr. With two ics can take different output voltage and amperage. This circuit is protected from short circuit p2 is for controlling the current at the range of 0 2a. This power supply circuit is highly stabilized that its output voltage will drop only 0 005 even though the load changes from 0 to 100.

Another excellent capability is that the output voltage will change only by 0 01 if the input voltage fluctuates. Laboratory power supply transformer used in the power supply circuit with 4 bd249 transistors on the output stage. It uses lm723 dc voltage regulator ic 2n3055 power transistor x2 to increase current up. I use the lm10 ic because it has a reference voltage and that s useful for dc power supply.

It will keep a stable voltage when it has any load. Dc power supply 0 30v 5a adjustable regulator. So could you help me to solve the problem. I think i may have misread the scheme in the electrical or electronic circuit books.

To cater that i have designed an adjustable 50v 5a power supply with a variable output from 0v to 50v and adjustable current limiting from 0a to 5a. Furthermore it s built with an over load and over current protection benefits. The post explains a simple yet very useful 0 to 50v dual power supply circuit which will enable a full 0 to maximum dual voltage control of the input power supply dc. The basic design of the offered 0 to 50v variable dual power supply circuit with 0 to 10 amp variable current facility is demonstrated in the above figure.

What is a variable power supply. It also includes a wide range current control feature right from 0 to 10 amps. Adjustable power supply circuit. Also the important is the overload protection.

Transistor variable power supply 1a 0 30v. This is dc power supply 0 30v 5a an adjustable regulator is special that the output to 5a current. Single output can be used 2x25vac. Simply said it is a power supply that can adjust the output voltage or current.

This regulator is 0 50v variable power supply circuit which you can adjust output voltage in a wide range between 0v to 50v and a current at least 3a. The whole design is transistor bjt based and is practically unbreakable. So do the current too much than this circuit easy circuit. This is a simple 0 50v 2a bench power supply circuit diagram.
