Dynamo Voltage Regulator Circuit

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

Dynamo voltage regulator circuit.

It may use an electromechanical mechanism or electronic components. A voltage regulator may use a simple feed forward design or may include negative feedback. In this case the variable is generator output voltage. 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.

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. It controls output by sensing the voltage v out at a power generating coil and comparing it to a stable reference. Simple electromechanical relay circuits such as this one were very common in automotive electrical systems during the 1950 s 1960 s and 1970 s.

Where a system takes action to oppose any change in a certain variable. 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. A voltage regulator is a system designed to automatically maintain a constant voltage level.
