What is the type of converter shown in the given figure?

The correct answer is option 2):(Cyclo converter)

Concept:

Cycloconverter:

• A cycloconverter is a device that converts input power at one frequency to output power at a different frequency with one stage conversion.
• Cycloconverters are mainly of two types
• step down cycloconverter (output frequency (f0) < input frequency (fs) )
• step-up cycloconverter (output frequency (f0) > input frequency (fs) )

​

• The circuit consists of a single-phase transformer with a mid tap on the secondary winding and four thyristors
• Two of these thyristors P1 & P2 are for the positive group. Here positive group means when either P1 or P2 conducts, the load voltage is positive.
• The other two thyristors N1 & N2 are for the negative group. Load is connected between secondary winding mid-point O and terminal A.

Additional InformationBoost converter:

• The boost converter is used to "step-up" an input voltage to some higher level, required by a load. T

Buck converter:

• It is a switch mode DC to DC electronic converter in which the output voltage will be transformed to a level less than the input voltage. It is also called a step-down converter.

Cuk converter:

Cuk converter is used for the voltage regulation for the Dc application systems.
