Title:
INVERTER CONTROL DEVICE AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/281984
Kind Code:
A1
Abstract:
An inverter control device (23) is applied to a vehicle (10) provided with: a rotating electrical machine (21) which is an in-wheel motor provided integrally to a drive wheel (11) and which comprises a rotor (60) that has a magnet part where a plurality of magnetic poles are formed, and a stator (71) that has stator windings of a plurality of phases and is not provided with teeth protruding toward the rotor side in the radial direction; and an inverter (22) which is electrically connected to the rotating electrical machine. The inverter control device comprises: a control unit for performing PWM control to generate a drive signal for a switching element of the inverter, on the basis of a carrier signal and a command voltage of each of the phases and in all operating areas of operating points determined by the rotational speed and torque of the rotating electrical machine; and an operation unit for operating the switching element on the basis of the generated drive signal.
