Dynamo Voltage Regulator Circuit

It controls output by sensing the voltage v out at a power generating coil and comparing it to a stable reference.

Dynamo voltage regulator circuit.

The fundamental principle upon which their operation is based is called negative feedback. It may use an electromechanical mechanism or electronic components. In this case the variable is generator output voltage. Adjustable voltage regulator circuit using lm317.

Generally electronic circuits using tubes or transistors require a source of d c. Where a system takes action to oppose any change in a certain variable. 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.

Well this is a collection of voltage regulator circuits using the lm317 ic which is an adjustable voltage regulator. A voltage regulator may use a simple feed forward design or may include negative feedback. The voltage regulator as it names suggests regulates the fluctuating voltages supplied by the dynamo into something more usable by the motorbikes electrical system. A voltage regulator is a system designed to automatically maintain a constant voltage level.

Simple electromechanical relay circuits such as this one were very common in automotive electrical systems during the 1950 s 1960 s and 1970 s.
