Dynamo Voltage Regulator Circuit

The fundamental principle upon which their operation is based is called negative feedback.

Dynamo voltage regulator circuit.

The voltage regulator as it names suggests regulates the fluctuating voltages supplied by the dynamo into something more usable by the motorbikes electrical system. Generally electronic circuits using tubes or transistors require a source of d c. Simple electromechanical relay circuits such as this one were very common in automotive electrical systems during the 1950 s 1960 s and 1970 s. In this case the variable is generator output voltage.

Lm317 is a three terminal adjustable regulator from national semiconductors and it s input can range up to 40 volts. Depending on the design it may be used to regulate one or more ac or dc voltages. Adjustable voltage regulator circuit using lm317. A voltage regulator is a system designed to automatically maintain a constant voltage level.

Where a system takes action to oppose any change in a certain variable. It controls output by sensing the voltage v out at a power generating coil and comparing it to a stable reference. A dc voltage regulator is a device which maintains the output voltage of an ordinary power supply constant irrespective of load variations or changes in input a c. 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.

It may use an electromechanical mechanism or electronic components.
