MULTIPLE CURRENT TYPE INVERTER

摘要

PURPOSE:To obtain good output waveform by suppressing the ripple of DC current with ease by separating smoothing reactor for the ripple between converter and inverter from the reactor for the ripple occurring due to multiplication. CONSTITUTION:The DC reactor is seaparated into the DC reactor 307 and the interphase reactor 309 and into the DC reactor 308 and the interphase reactor 310. The windings of the interphase reactors 309 and 310 are wound for magnetic connection. In the inverter with such a connection, the ripple between the converter and the inverter is smoothed by the DC reactors 307 and 308, and the ripple occurring due to multiplication is smoothed by the interphase reactors 309 and 310.
