DEVICE, METHOD, AND PROGRAM FOR CONTROLLING CONVERTER, AND AIR CONDITIONER

摘要

To control the power factor to about 1 irrespective of a load. A converter control device (4) includes: a reactive current calculation unit (21) that calculates a reactive current Iq by using current detection values Ir and It of R-phase and T-phase and an R-phase voltage phase ¸, a correction amount calculation unit (22) that calculates a phase difference of the R-phase voltage phase for zeroing the reactive current Iq as a phase correction amount ¦, a phase correction unit (23) that corrects the R-phase voltage phase ¸ by using the phase correction amount calculated by the correction amount calculation unit (22), a three-phase voltage command determination unit (24) that determines phase voltage commands corresponding to the respective phases based on a predetermined voltage command value k and a corrected R-phase voltage phase ¸', and a PWM signal generation unit (25) that generates driving signals for the switch units corresponding to the respective phases by using the phase voltage commands.
