Three phase full bridge inverter-120 degree mode
Inverter is a device that converts dc power into ac power at desired output voltage and frequency. The output voltage waveform of an ideal inverter should be sinusoidal. However, the waveform of practical inverter are non sinusoidal and contain certain harmonics. For low and medium power applications, square wave or quasi square wave voltages mayContinue reading “Three phase full bridge inverter-120 degree mode”

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 itsContinue reading “Switched Mode Power Supply (SMPS)”
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 changesContinue reading “Comparison :Buck, Boost, Buck-Boost Converters”
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 voltageContinue reading “Buck-Boost Converter”
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 largeContinue reading “Boost Converter”
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 connectedContinue reading “Buck Converter”
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 InContinue reading “Types of Chopper”
