要約(英語): A large current generating apparatus is used for a power system testing apparatus or a power supply apparatus for a magnetic inspection apparatus, and supplies a large current output to a low resistance load. The transformer used for large current output is driven at commercial frequency and the challenge is to improve power efficiency.In this paper, by changing the wave-form of driving voltage for the transformer used in the high power output equipment to the ternary pulse of the same frequency from the conventional sine wave, it was shown that the iron loss of transformer could be reduced applying by 14% while maintaining the effective value of the output current. In addition, it was also shown that by the unipolar PWM driving for the transformer, the iron loss could be reduced to 89% of that in bipolar PWM system with the miniaturization of the transformer size.
