Title:
POWER CONVERSION EQUIPMENT AND DYNAMO-ELECTRIC MACHINE SYSTEM
Document Type and Number:
Japanese Patent JP2019161927
Kind Code:
A
Abstract:
To provide power conversion equipment capable of reducing lifetime variation of multiple power converters connected in parallel, and to provide a dynamo-electric machine system.SOLUTION: Power conversion equipment 3 performing parallel driving of single load by multiple power converters 4a-4c connected in parallel includes a control arrangement 7 for adjusting load sharing of respective power converters, according to the temperatures thereof. The control arrangement adjusts load sharing of each power converter by controlling the output thereof according to the load sharing ratio of each power converter, and sets the load sharing ratio of the power converter of low temperature higher than that of the power converter of high temperature.SELECTED DRAWING: Figure 1
