CIRCUIT BREAKER TRAINER MODEL
DESCRIPTION:- The main contact in the IPC-1800-CBT is protected by means of an automatic shut-off against an overload. The three magnet relays and their contacts are easily accessible through the input / output terminals. This feature makes it possible to operate the circuit breaker with heavy loads. Another area application using this method is experiment the start/stop characteristics of an induction motor with three phase along with a Ã’Â®, Ã¢Ë†â€ transformation.

EXPALNATION OF THE POWER ELECTRONICS TRAINER
The Power Electronics Trainer IPC-550-PE has been specially developed for the measuring exercises in course. It form the basis for all basic circuits in the field of D.C and A.C power controllers as well as the 1-. 2-, 3- and 6-pulse power converter circuits in rectifier mode and inverter mode. It can be used not only for the passive loads but also for active loads.The unit is designed for the operation on the 3 x 38 / 22V mains, the connection being made via laboratory leads to the 4-mm plugs.
Care should be taken that, for reasons of the synchronization of trigger pulses, the unit is to be connected to the three outer conductors and the neutral conductor for all exercises. By virtue of the transparent front panel, the construction of the technical equipment can easily be seen and the arrangement of the plugs is the basis for each connection layout of all experiment circuits the printed symbols shall guarantee a quicker circuit construction without any problems.
Power Electronics Trainer Model:- IPC-550-PE
The conductor L1, L2 and L3 are applied to input of the communication chokes (Lk = 2mH; 10A) via fine wire fuses (4Aff) and the main switch. The control lamps H1-H3 indicate the function of the fuses and are lit in the case of a blown fuse. The limiting values for controlled valves V1-V6 are
URRN = UDRM = 1000V; ITAVM = 10A
And for uncontrolled valves V10-V60
URRM = 1000V; IFAVM = 10A
The AHS circuits consists, together for all twelve valves, of an RC element with the following data
RTSE = 100 ohms, 5W; CTSE = 0,047μF, 400V
The main currents, the valve currents and the load currents can be converted into a proportional measuring voltage by means of the built-in precision resistor 1 ohms. Since the voltage supply of the controlled unit is protected via fuse F4, switch S is used for pulse enabling and pulse inhibit.The twelve trigger-pulse outputs are electrically isolated from each other and are divided into three pulse groups. For example, pulse group U1 is assigned to phase voltage UL1N. The two upper pulses being in phase used to control the negative half-wave of the voltage. The plugs marked with "G" are provided for the gate terminal and the plugs marked with the "K" for the terminal at the cathode-side of the thyristor.The potentiometer R serves for the adjustment of the control angle of the phase voltages ranging from 0° ≤α ≤ 180.The two other potentiometers are provided for the matching of the control range to respective switching situation. Potentiometer α GR (GR = Rectifier) is used to adjust the pulse-finish position at the beginning whereas the pulse-finish position at the end is set by operating potentiometer α WR (WR = Inverter).
NOTES ON THE FURTHER TECHNICAL EQUIPMENT
The essential part of the circuits of exercises and test in course "Power Electronics" can be constructed using converter-Rectifier Trainer IPC-550-PE. For a number of additional exercises a modern laboratory with some additional power - converter equipment must be available.
Explanations for the Worksheets of Course IV:
The worksheets for the 16 practice circuits are given in the order of the circuit code numbers. The worksheets belonging to a circuit for exercise consists of two general pages with the proper worksheets.The general pages consist of a circuit diagram, a component layout or a terminal connection diagram, the specification of the equipment necessary for the exercises and a short description of the circuit and the exercises.The following worksheets consist of - divided into subsection - the respective task including the necessary technical information and the corresponding tables, diagrams or equation. The determined measured values and results have to be inserted there.The given exercises to the particular circuits are rather suggestion for the systematic procedure for exercises.It is not intend that each student should perform every single experiment in course. It is left to the instructor to select optimum number of exercises according to the method of teaching. These exercises can be carried out by the student in groups. Of course it is possible that each group of students does a different exercise. In any case the result of the exercise should be compared and discussed by the students among themselves.
