Appendix

Design and construction of a working power supply

system for the excitation of DC motors

This thesis deals with the analysis, design and construction of a working power supply system for the

excitation of a DC machine using a power electronics converter. The power of this converter is set at

250W while the output must be able to to vary between 20 and 250 Volts and the current from 0.02A to

1.1A.This work was performed at the laboratory of electromechanical energy conversion in the

Department of Electrical Engineering and Computer Technologies, University of Patras, Greece.

The aim of this project was to perform the necessary steps for an optimal design, proper parameter and

application demands estimation, both in state as well as in transient operation and finally the successful

implementation of the power circuit. Moreover, the goal was also to select the right components that

optimize the device operation, in terms of both cost and system efficiency. Initially, we studied different

types of already existing electronic converters that met the application requirements. After that, we chose

the most appropriate one, offering most benefits among others. Such comparison elements that were used

are, for example, the efficiency, the design complexity, the cost, the simplicity and flexibility of the

control but also the construction into the laboratory. Considering all the above we selected a type

“forward” converter with two semiconductor switching controllers. We analyzed and modeled this

converter which was designed in detail and we selected components that ensure the efficiency and

security of the power circuit. We also designed the optimal architecture of the PCB placket which was

constructed in the laboratory. All the magnetic components, the high frequency transformer and

conductor were designed and constructed, using the “area code” selecting method. The input and output

filters as well as the EMC filter, that cancels the common and differential noise, were also designed and

constructed.

The next step dealt with the control of the converter. Various control strategies were studied in order to

choose the one most appropriate for the needs of the application. We chose the most suitable

microprocessor and programmed optimal code for its control. After that, the controller circuit was

fabricated in the laboratory. The control strategy that was chosen ensured the measure of the average

power of the current using the PWM (pulse width modulation) control. The industrial microprocessor

DSPIC30F4011 was used.

Finally the entire construction (supply and control circuit) functioned together, measurements were

recorded and the graphs of the experimental operation were compared with the theoretical. The

effectiveness of the converter as a whole was also measured and evaluated..
