An isolation system for gate drivers of a three-phase medium-voltage inverter is proposed in this paper. The power consumption in gate drivers are supplied beyond an air-gap of 50 mm from the one transmitting board to the six receiving boards using transmission coils on the printed circuit boards. It contributes a cost reduction of an isolation system. In this paper, the proposed system is experimentally demonstrated. In order to evaluate the effect of the materials of the chassis, especially, two types of the chassis made from aluminum and acrylic are tested. As a result, the maximum efficiency is improved from 29.4% to 46.9% by changing the materials from aluminum to acrylic.
Moreover, a three-phase inverter is operated with the proposed isolation system in order to clarify the utility of the system. |
