Simple Automatic Voltage Regulator Diagram

This is the most simple voltage regulator circuit diagram in our website.

Simple automatic voltage regulator diagram. You can adjust the output voltage by varying the pot. A voltage regulator is a system designed to automatically maintain a constant voltage level. The automatic voltage regulator works on the principle of detection of errors. Lm117 is a reliable ic which can output regulated voltage in the range of 1 2 volts to 37 volts.

Just got an ic lm117 and 4 passive components. It controls the voltage of the system and has the operation of the limit nearer to the steady state stability. To begin with an electrical current flows through the resistor r1 to limits current to the zener diode. In this post we learned how to build simple linear voltage regulator circuits using series pass transistor and zener diode.

12v 1a linear voltage regulator using 2n3055 transistor and zener diode. As the circuit diagram below the input terminal wants an unregulated dc supply 15v to 20v. A voltage regulator may use a simple feed forward design or may include negative feedback. The series regulator transistor should be specified to support the highest output current imax and should be mounted on a heatsink where it may dissipate 5 5 x isec watts.

The automatic voltage regulator is used to regulate the voltage. Then the regulated voltage will come out to the load. A switching voltage regulator circuit shown in the schematic diagram here can be a low cost solution for your high efficiency requirement electronic circuit design. The above automatic voltage regulator circuit clearly shows that ac 12v enters through 500ma transformer to auto cut circuit.

Depending on the design it may be used to regulate one or more ac or dc voltages. It takes the fluctuates voltage and changes them into a constant voltage.
