4.Bench for the study of choppers 0.5 kW mini:

Bench allowing a complete study of choppers with different types of semiconductor power used in industry and with different loads of minimum power 0.5 kW. The bench shall include:

. A power module (0.5 kW mini) must have at least three (03) of the semiconductor technologies most used in practice (eg transistors IGBT transistor FET, GTO thyristor, Darlington transistor, etc.) Circuits, the current-voltage measuring transformers and the inputs for the signals transmitted from the control module

The module must be supplied with masks corresponding to semiconductor technologies. Power-driven seedlings must be protected against over-current and short-circuiting. The current measuring sockets must be isolated from the power circuit (eg galvanic separation).

. A power semiconductor control module with its masks ensuring: . Manual duty cycle and cyclic frequency control;

 . Current control with analog input of the reference variable;

. PI-type speed control with cascaded current regulation;

 All measuring points must be available on 4 mm safety sockets

Bench for the study of choppers 0.5 kW mini:

5.Accessories:

. Bridge rectifier with flutter capacitor for having a DC voltage source;

. Three-phase power isolation transformer suitable for the bench;

. Variable resistive load of suitable power to the bench;

. Variable inductive load of suitable power to the bench;

. Continuous current machine with shunt power suitable for the bench;

. Sensor for controlling the speed of rotation (to ensure a control loop);

. Specific connection and operating accessories (safety cords of different lengths, fixing elements of the devices, etc.)
