Experimental evaluation highlights the impact of resonant capacitors on generation characteristics in electric vehicles, suggesting improved performance.
In nonelectrified railway lines, advancements are underway for the electrification of vehicles to reduce their environmental impact, along with research and development for the practical application of electric vehicles powered by diesel generators and battery. A series-resonant permanent magnet synchronous generator (PMSG) system, consisting of a permanent magnet synchronous generator, full-wave rectifier, and resonant capacitor, is expected to be highly efficient and cost-effective, making it well-suited for applications in electric vehicles. However, the generation characteristics of series-resonant PMSG systems have not been evaluated in terms of total harmonic distortion. Therefore, this study experimentally investigated these characteristics. The experimental results revealed that the output can be enhanced by connecting a resonant capacitor, even in the presence of harmonics.
