A functional block schematic of the series type regulator is shown in Figure. Vo is the regulation output voltage, whereas Vin is an unregulated dc output. The control element moves as needed to keep Vo constant in a series path between Vin and Vo. A reference voltage is compared to the feedback voltage that a sampling circuit produces, which is proportional to Vo. The control signal from the comparators circuit is what modifies the control element's operational state. If the load increases and Vo falls, the comparator generates an output that instructs the control element to raise Vo.

Shunt Regulator:

Figure depicts the shunt regulations' functional block diagram. All of the components in this system function as series regulators, but the control element is connected to the load in parallel. By shunting more or less current away from the load, the control element keeps the voltage across the load constant. By shunting more or less current away from the load, the control element keeps the voltage across the load constant.

The control element can be conveniently viewed as a variable resistance. The control element's resistance is designed to increase when the load voltage drops. As a result, the load voltage increases and less current is diverted away from it. In contrast, as the load voltage rises, the control element's resistance falls and more current is diverted away from the load.
