Jones Chopper Circuit Diagram

This circuit is an example of voltage commutation.

Jones chopper circuit diagram. Fig 1 shows the circuit diagram of the jone s chopper thyristor t1 is the main power switch corresponding to s1 thyristor t2 is the auxiliary thyristor. Applications of jones. When the two choppers are on the output voltage v 0 will be equal to v s.

The jones chopper circuit is frequently used for the speed control of dc motors. Jones chopper circuit working choppers and types ac and dc chopper circuits. Here t1 is main thyristor and t2 is auxiliary thyristor.

Type d chopper or two quadrant type b chopper two quadrant type b chopper or d chopper circuit. Basics of jones chopper 2. T1 is the main thyristor and t2 is the auxiliary thyristor.

Circuit of jones chopper 3. Power electronics and drives lab kct college of engineering. Let us assume that the given polarities in the diagram are positive.

The circuit operates in the following modes. The scr t1 is main scr whereas scr t2 diode d1 capacitor c and auto transformer t makes commutating circuit for scr t1. Working of jones chopper 4.

When v 0 v s the two choppers will be off but both the diodes d1 and d2 will start conducting. The circuit diagram of the type d chopper is shown in the above figure. Chopper circuit principle of operation.
