Abstract
This paper presents the core loss mathematical model design and the prediction of core loss with PMW Inverter supply. In the procedure, the 1-phase bipolar PWM inverter supply is used to supply the Epstein test apparatus with the 0.23 mm., 0.27 mm., 0.30 mm.-thick sheet, grain oriented magnetic steel, and 0.5 mm.-thick sheet, Non oriented magnetic steel. By setting the equal maximum magnetic density for each test procedure, with 0.3, 0.6, 0.9- modulation index and 1-9 kHz inverter switching frequency, the test results are shown that the core loss by the prediction is nearly the same that by the experiment, with 0.3, 0.6, 0.9- modulation index, so this mathematical model design is more useful and can be applied to the design work in electrical machine equipment.
