Title:
INVERTER CONTROL METHOD AND INVERTER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/155522
Kind Code:
A1
Abstract:
Provided are an inverter control method and an inverter control device. The inverter control device (31) receives input of an ON signal and an OFF signal from a controller (10) and determines an output command value for an inverter output (32) on the basis of the signals. If the OFF signal is input, the output command value for the inverter output (32) is a prescribed minimum value, and if the ON signal is input, the output command value for the inverter output (32) is determined on the basis of a time interval associated with the ON signal and the OFF signal. Moreover, the inverter control device (31) sets the output command value for the inverter output (32) to the OFF value when current in a C-phase which is provided with an internal overload protector (41) is blocked and R-phase current flow is detected.
