Power supply systems consist of numerous devices and components needed for efficient operation. One such device is the voltage regulator. These regulators play a crucial role in ensuring equipment's efficient and safe operation. If you are eager to learn about these devices in detail, continue reading this post. It will start by explaining what a voltage regulator is and then go on to explain all the other things about it.Â
A voltage regulator is an electronic device that transforms input power into the desired voltage level for output. These regulators play an essential role in power supply systems. Even during power changes and differences in loads, the control voltage. A voltage regulator stabilises a higher input voltage, resulting in a lower output voltage. Â
The main components of a voltage regulator are-
Voltage regulators ensure that an electronic device receives a constant and stable voltage regardless of fluctuations in the input voltage and load conditions. These regulators automatically adjust the current flow and maintain a consistent output voltage. But what do voltage regulators do to stabilise voltage? They follow the steps below for their operation.Â
Reading these steps should have familiarised you with what a voltage regulator does. Now, move on to the next section to learn about the different types of these regulators.Â
Voltage regulators are primarily categorised into the following two types.Â
Linear Voltage Regulators were the first form of regulator employed in power supplies. In these regulators, the adjustable conductivity of the effective pass element, usually a Bipolar Junction Transistor (BJT) or Field Effect Transistor (MOSFET), is responsible for maintaining an optimum output voltage.
Whenever a load is attached, any variations in the input voltage or load may cause changes in the present streaming through the transistor to ensure that the output voltage stays constant. Because of this regulation, the transistor should operate in the Ohmic or active region (also referred to as the linear region), where it can modify its existing current.Â
Nevertheless, this method leads to considerable energy loss, as the big difference between the input and output voltage is dropped across the transistor and dissipated as heat.
Linear voltage regulators are generally categorised into the following five types:
Also, based on how the load is connected, these regulators are classified into-Â
The Switching Regulator presents a divergent narrative as compared to linear voltage regulators. Here, the pass transistor assumes the dual role of a switch, alternating between states of On and Off. By finely tuning the ON time of this transistor, the output voltage maintains a steadfast constant.
Based on their design, switching voltage regulators are of the following two types:
The most common applications of voltage regulators are as follows.Â
