| Research Abstract |
In this study, novel and advanced technologies those are valuable on the increase of power density of the inverters are developed. Technical achievements on this study is as follows
(1) Accurate loss calculation method and loss measuring method of the AC filter inductors used in both of the single-phase and three-phase PWM inverters. Based on the above method, optimum design method of the ac filter inductors is developed.
(2) Accurate measuring method of both the parasitic inductors and parasitic capacitors those are lying on the printed circuit board of the inverter is developed. Effectivenessof the proposed methods is verified through the experiments.
(3) Advancement of the fundamental technology which is useful for increasing the power density of the inverters has been provided. Further development which relates to the development of loss calculation method on the gapped-core material and simulation method of magnetic flux distribution will be our future works.
