Dynamo Voltage Regulator Circuit

A voltage regulator is a system designed to automatically maintain a constant voltage level.

Dynamo voltage regulator circuit. Adjustable voltage regulator circuit using lm317. In this case the variable is generator output voltage. 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.

Depending on the design it may be used to regulate one or more ac or dc voltages. 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. 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. Lm317 is a three terminal adjustable regulator from national semiconductors and it s input can range up to 40 volts.

Simple electromechanical relay circuits such as this one were very common in automotive electrical systems during the 1950 s 1960 s and 1970 s. The voltage regulator as it names suggests regulates the fluctuating voltages supplied by the dynamo into something more usable by the motorbikes electrical system. The fundamental principle upon which their operation is based is called negative feedback. 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.

A voltage regulator may use a simple feed forward design or may include negative feedback.
