POLYPHASE VOLTAGE CONVERTING APPARATUS AND VEHICLE

摘要

A polyphase voltage converting apparatus (10) is provided with a plurality of voltage converters (31-33) connected in parallel between a first node and a second node; and a controller (30) which selects one or two voltage converters to be driven from the voltage converters (31-33) based on the detection results of the status of the voltage converters (31-33). Preferably, each of the voltage converters (31-33) includes an element temperature sensor (41) for measuring element temperature. The controller (30) decides the voltage converter to be driven based on each element temperature of the voltage converters. The controller (30) decides the voltage converter to be driven so that the voltage converters are used from the one having a lower temperature by giving priority. Thus, while suppressing cost increase, the polyphase voltage converting apparatus having a long product life and a vehicle are provided.
