永久磁石同期機と倍電圧整流回路を用いたディーゼル発電システム

抄録

In this study, we propose a diesel generator system using a permanent magnet synchronous machine and voltage multiplier circuit for application in diesel electric and hybrid vehicles. In the voltage multiplier circuit, capacitors inserted between full-bridge rectifiers and the permanent magnet synchronous machine act as phase-shift capacitors for enhanced power generation and potential isolation capacitors for voltage multiplication. The proposed system has the advantage of being able to achieve a high DC voltage even when the voltage output by the generator is low. In this paper, we outline the proposed system, and reports on the results of theoretical analysis to design a power generation system for a diesel electric railcar. We also report on simulation-based operational verification.
