CURRENT & VOLTAGE COMMUTATION EXPERIMENTER. MODEL IBL-PE- 21

This trainer is intended to experiment and see how the current and voltage commutation circuit performs for different load conditions. This trainer has basic (a) Thyristorised power circuit with necessary commutation, (b) Chopper triggering circuit for SCR applications, and (c) a power supply for the triggering circuit only.

This requires an optional variable high voltage DC power supply. It must be in the range of 0 to 240V DC operating at 3A under peak load conditions. This will be used as power source for applying to different types of loads. These loads can be pure resistive or combination of R-L-C. All these are optional.

Using this trainer it is possible to observe load voltage, load current, commuting capacitor voltage, commuting capacitor current, for pure resistive loads using an Oscilloscope. For this you need suitable extra Voltmeter and Ammeter. The interconnections are established by using suitable patch cords. All the necessary circuit points are terminated on 4mm banana sockets for interconnections
