Morgan chopper is the example for the current commutated chopper.

Circuit diagram jone chopper. T 1 is the main thyristor and t 2 is the auxiliary thyristor. Dc chopper firing unit provided triggering pulses for this power circuit. Examples of such applications are subway. Essentially a chopper is an electronic switch that is used to interrupt one signal under the control of another.

Chopper circuit principle of operation. It will help to improve controllability of the equipments also. The performance of these applications will be improved if we use a variable dc supply. The special feature of this circuit is the tapped auto transformer.

The circuit operates in the following modes. Remember that jones chopper is the example for voltage commutated chopper. We have seen already about the basic of chopper circuits various types of chopper circuits. Jones chopper working principle tutorial.

The principle of operation of chopper can be understood from the circuit diagram below. Let us assume that the given polarities in the diagram are positive. Fig1 shows the circuit diagram of the jones chopper thyristor t1 is the main power switch corresponding to s 1 thyristor t 2 is the auxiliary thyristor. The circuit consists of a semiconductor diode resistor and a loadfor all type of chopper circuit the output voltage value is controlled by periodic closing and opening of the switches used in the circuit.

The circuit diagram of jones chopper is as shown in the figure. A chopper is a device that converts fixed dc input to a variable dc output voltage directly. In this post let us discuss about the operation of jones chopper.
