Dynamo Voltage Regulator Circuit

Adjustable voltage regulator circuit using lm317.

Dynamo voltage regulator circuit.

A voltage regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed forward design or may include negative feedback. Well this is a collection of voltage regulator circuits using the lm317 ic which is an adjustable voltage regulator. Where a system takes action to oppose any change in a certain variable.

In this case the variable is generator output voltage. It may use an electromechanical mechanism or electronic components. Lm317 is a three terminal adjustable regulator from national semiconductors and it s input can range up to 40 volts. Generally electronic circuits using tubes or transistors require a source of d c.

The fundamental principle upon which their operation is based is called negative feedback. It controls output by sensing the voltage v out at a power generating coil and comparing it to a stable reference. Depending on the design it may be used to regulate one or more ac or dc voltages. An automatic voltage regulator avr is a electronic device for automatically maintaining generator output terminal voltage at a set value under varying load and operating temperature.

In the most basic terms it consists of two electrical contacts switches which are opened and closed turned off and on by two sets of solenoid coils.
