There are wide range of choppers which are used for different applications. These circuits differ in the voltage level, method of functioning and the output waveform.
Choppers can be classified into the following types
Step Up or Step Down Choppers
Step up Choppers, as the name suggests, step up the voltage. These choppers are used when the voltage has to increased to a higher level.
AC and DC Choppers
Choppers can be classified into AC and DC choppers depending on the supply
Circuit Operation
On the basis of Circuit Operation, Choppers can be classified into
- First Quadrant
- Second Quadrant and
- Fourth Quadrant
On the Basis of Commutation
- Impulse Commutated Choppers
- Voltage Commutated Choppers
- Current Commutated Choppers
- Load Commutated Choppers
Depending on the Direction of Current
Class A
Class B
Class C
Class D and
Class E
In recent times, Choppers are usually classified based on their application such as switched mode power supplies, Class D Electronic Amplfiers, etc.
