CONTROLLER FOR ELECTRIC VEHICLE

Document Type and Number:

Japanese Patent JP2022109864

Kind Code:

A

Abstract:

To reduce multiple components of an electric frequency.SOLUTION: A controller 40 for an electric motor 1 includes: a direct current power source 10; a motor 30; an inverter 20 for converting a DC power supplied from the direct current power source 10 into an AC power and outputting the current to a motor 30; and an inverter control unit 100 for controlling the inverter 20 and controlling an input voltage to the motor 30. The inverter control unit 100 makes a correction of applying a component that cancels out a high frequency component on an input voltage if a parameter correlated to the input voltage includes a specific frequency component, and then controls the motor 30 on the basis of the corrected input voltage.SELECTED DRAWING: Figure 1
