Title:
CURRENT VALUE DETERMINATION DEVICE, CONTROLLER, ELECTRIC COMPRESSOR, CURRENT VALUE DETERMINATION METHOD, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/049622
Kind Code:
A1
Abstract:
A current value determination device provided with: a capacitor current computation unit for computing the capacitor current of a capacitor included in a high-voltage circuit that drives a motor, on the basis of the input voltage of an inverter included in the high-voltage circuit and the revolution speed of the motor; and a capacitor current determination unit for determining the value of capacitor current on the basis of the input voltage of the inverter, the revolution speed of the motor, the capacitor current computed by the capacitor current computation unit, and a prescribed model for determination.
