Theory of switching mode voltage regulator

ENEL372 Power and Analogue Electronics: Voltage Regulator

Topic: Switch Mode Voltage Regulator

Provide a stable and regulated output voltage of required value to the design circuit. It serves many purposes like regulation, stepping down to required voltage, stabilizes the voltage and protection against surges etc.

Answer:

Introduction

A switched mode power supply is an electronic based power supply. It incorporates a switching regulator to convert electrical power accurately. The regulator contains LC circuit, which maintains the necessary output voltage with the help of charging and discharging the capacitor and inductor. Where, the switching mode power supply transfers power from a DC Source to AC Source. The inductor’s DC pulse is charged and in turn provides stable output capacitor. In case, when the DC pulse is turned off the Schottky diode di

Switching Regulators- Types

Switched mode voltage Regulator can be classified based on different aspects like, functions used and input power supply. Based on the type of the input power supply DC/DC converters and AC/DC converters are the classified types. These two converters consist of both non-isolated and isolated types. Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) are the different types of operations used in Switching Mode Voltage Regulator. Different types of conversions used in Switching Mode Voltage Regulator are Buck, Boost and Inverting conversions. Buck Converter known as the step-down converter, drops down the voltage from its supply (input voltage) to Load (output voltage). Boost Converter is a step-up converter, which raises the voltage. It is equivalent to a flyback converter ("Types of Switching Regulators", 2017).
