| Abstract: | In order to improve the harmonic characteristics of the networkside current, multiple cascade technology is introduced by CRH2 EMU. This article analyzes the influence of multiple controlstrategy on the content of side current harmonics. Extensive analysis and experiments prove that theuse of multicarrier phaseshift control strategy significantly offsets a large number of characteristicharmonics and reduces the content of side harmonics with specific frequency band. Test results showsthat better harmonic characteristic of the networkside current is obtained and the networkside currentquality is improved. |
