Abstract

Power electronics classes have available laboratory exercises for DC-DC converters the problem is there are no available converter modules to be used for the application of these exercises. Flyback converter modules were designed, fabricated and tested to address the problem. The load regulation, efficiency, duty cycle, frequency and the drain-to-source voltage of the MOSFET were determined to evaluate the performance of the flyback converter module. These parameters were measured at three different load conditions: full load, half load, and 25% full load. The duty cycle and frequency were measured using the Vgs wave form, Vps waveform, and the average and peak input current. The effect of the snubber circuit was tested by measuring the Vps. The results of the three methods done to measure the duty cycle and frequency agreed with each other. The drain-to-source voltage did not exceed the MOSFET's breakdown voltage in all the snubber resistor tested. The load regulation of the flyback converter module is -6% and the efficiency at full load reached 60%. In terms of effectiveness, the module is still useful in performing laboratory exercise for dc-dc converters. The basic operation of flyback converter can still be learned during the evaluation of the flyback converter through performing laboratory exercises.
