Introduction to inverter

Nowadays, all the home appliances are marketed as efficient devices and they employ inverter technology. In this article, we will see what is an inverter and the basic introduction to designing a square wave inverter. Inverter is a device that converts dc power into ac power at desired output voltage and frequency. Why do we

Switched Mode Power Supply (SMPS)

All electronic devices require power supply for its operation. Some of the devices are fed from battery and some may be given power directly from the ac outlet. where an inbuilt rectifier will convert ac to dc and produce a regulated dc output. All the Integrated Chips (IC) need a regulated power supply for its

Comparison :Buck, Boost, Buck-Boost Converters

DC-DC converters are power electronic converters which  convert a fixed DC voltage to a variable DC voltage. Buck, Boost and buck-boost converters are the three basic dc-dc converters which converts a fixed dc voltage to a variable dc voltage. Each of the converters has same number of components however, the position of the components changes

Buck-Boost Converter

DC-DC converters are power electronic converters which  convert a fixed DC voltage to a variable DC voltage. Buck-Boost converter is a DC-DC converter which produces a DC output voltage greater than or less than the input DC voltage. Read about buck converter/stepdown converter Read about boost converter/step down converter Buck-Boost converter produces a output voltage

Boost Converter

DC-DC converters are power electronic converters which  convert a fixed DC voltage to a variable DC voltage. Boost converter is a DC-DC converter which produces a DC output voltage greater than the input DC voltage. Hence boost converter is also called as step-up converter. Read about buck converter/step down converter Boost converter requires a large

Buck Converter

DC-DC converters are power electronic converters which  convert a fixed DC voltage to a variable DC voltage. Buck converter is a type of DC-DC converter which produces a DC output voltage less than the input DC voltage. Hence a buck converter is also called as step-down converter. A low pass LC filter is usually connected

Types of Chopper

Chopper is a power electronic converter which converts fixed DC voltage to variable DC voltage. Chopper uses thyristors for power conversion. As thyristors can carry current in only one direction, by properly arranging the thyristors and diodes, four quadrant operation of chopper can be achieved. Types of chopper based on the quadrant of operation In

Introduction to Choppers

Many applications require DC power for its operation. For example: Battery charger, Battery operated vehicles, trolley buses etc.Each device may require different voltage level and a variable dc source can meet the requirements of different devices. What is a Chopper? A DC chopper is a static power electronic device which converts fixed DC voltage to

Dual converter

A three phase fully controlled converter can operate in two quadrants ( I and IV). The average output voltage can be positive or negative depending upon the firing angle while the current remains always positive because of the unidirectional property of the devices. How to get four quadrant operation? There are some applications like a

Effect of source inductance on the performance of phase controlled rectifier

In single phase fully controlled rectifiers, 2 thyristors conduct at any time. When the other two thyristors are triggered, the outgoing thyristors will turn off immediately. It is assumed that the incoming thyristors are turned on instantaneously and outgoing thyristors are turned off instantaneously. However, this is applicable only when the source does not have
