Types of Chopper
Types of Chopper Circuits in Power Electronics ... Type -C chopper or Two-quadrant type-A Chopper . Type C chopper is obtained by connecting type –A and type –B ...
The type E chopper is a four quadrant chopper. The type E chopper is parallel combination of two typeC chopper. The combination of chopper CH1, chopper CH2, diode D1 and diode D2 makes one type C chopper and other is made from chopper CH3, chopper CH4, diode D3 and diode D4.
In type B or second quadrant chopper the load must always contain a dc source E . When the chopper is on, v 0 is zero but the load voltage E drives the current through the inductor L and the chopper, L stores the energy during the time T on of the chopper .
Type -C chopper or Two-quadrant type-A Chopper Type C chopper is obtained by connecting type –A and type –B choppers in parallel. We will always get a positive output voltage V 0 as the freewheeling diode FD is present across the load.
