Two types of regulators are used: step regulators, in which switches regulate the current supply, and induction regulators, in which an induction motor supplies a secondary, continually adjusted voltage to even out current variations in the feeder line.
What are types of regulator?
2. Switching voltage regulatorsBuck switching voltage regulators. Buck switching regulators, also known as step-down regulators, convert a high voltage at their input terminals to a lower voltage at their output terminal. Boost switching voltage regulators.

How do regulators work?
A voltage regulator generates a fixed output voltage of a preset magnitude that remains constant regardless of changes to its input voltage or load conditions. There are two types of voltage regulators: linear and switching.
What is linear and switching regulator?
Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity, unlike linear regulators. The versatility of these converters allow configuration for buck, boost, buck-boost, flyback, inverting in isolated and non-isolated applications.
How Zener diode works as a voltage regulator?
When forward biased, it behaves like a normal signal diode, but when the reverse voltage is applied to it, the voltage remains constant for a wide range of currents. Due to this feature, it is used as a voltage regulator in d.c. circuit.
What is the working principle of switching regulator?
Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity, unlike linear regulators. The switching voltage regulator switches on and off rapidly to alter the output. It requires a control oscillator and also charges storage components.
Why do we use regulators?
Voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.
What is difference between regulator and converter?
A step down converter—also known as a buck converter—converts high voltage to low voltage, usually transforming AC current to DC current. A voltage regulator maintains a constant output voltage for a circuit, regardless of any changes in connected devices or electrical load.
Why do we use switching regulators?
A switching regulator can convert input direct current (DC) voltage to the desired direct current (DC) voltage. In an electronic or other device, a switching regulator takes the role of converting the voltage from a battery or other power source to the voltages required by subsequent systems.
What are the four basic types of switching mode regulator?
Also, a current mode, a voltage mode, and hysteresis (or ripple, or comparator) control mode are among the available feedback control methods designed to regulate the output. These will also be discussed later.
What is the use of regulator?
Voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.
What is main function of the current regulator?
- Current regulator. The purpose of a current regulator is to provide a constant current regardless of changes in the input voltage or load current. The schematic shown in figure 4-42 is that of a circuit designed to provide a constant current of 400 milliamperes.
How efficient is a voltage regulator?
between 80-90% Most switching regulators have an efficiency between 80-90%. The efficiency of a linear regulator varies with the ratio of the input voltage to the output voltage.
Where are switching regulators used?
A switching regulator can convert input direct current (DC) voltage to the desired direct current (DC) voltage. In an electronic or other device, a switching regulator takes the role of converting the voltage from a battery or other power source to the voltages required by subsequent systems.
