The shunt regulator operates by maintaining a constant voltage across its terminals and it takes up the surplus current to maintain the voltage across the load. An alternative is the SCR shunt regulator which uses the regulator output as a trigger. The lower is the output of the regulator. Subsequently, the output voltage could be the sum or difference between the winding voltages. Find schematics for your product. That is the reason behind naming it a DC Shunt motor. regulators for voltage improvement. If you want to use more, then R1 and R2 will have to be reduced in value. Zener diode is a kind of diode which permits the current to flow in forward direction as well the reverse direction when it reaches the zener voltage. It employs FET in Ohmic region.
