Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/040169
Kind Code:
A1
Abstract:
A control device is provided with: a carrier frequency setting unit (52) that sets a frequency selected from among a plurality of carrier frequencies, individually, to each of a plurality of inverters; and a switching timing table (100) that prescribes, for each of a plurality of carrier frequency sets, a switching timing, which is the timing allowed upon switching to a different set of carrier frequencies. The switching timing table (100) is a table that prescribes the switching timing so that current-detection processing to be conducted for each of a plurality of AC motors is conducted so as to match the maximum value or minimum value of the carrier configured for the relevant inverter, and the carrier frequency setting unit (52) switches the settings for the carrier frequencies (Fc), on the basis of the switching timing obtained from the switching timing table (100).
