Title:
APPARATUS AND CONTROL METHOD OF THE SAME
Document Type and Number:
WIPO Patent Application WO/2021/071207
Kind Code:
A1
Abstract:
An apparatus capable of efficiently reducing leakage current and noise in various environments by shifting a pulse signal of an inverter configured to control a three-phase drive motor, and a control method of the same are provided. In accordance with an aspect of the disclosure, an apparatus is provided. The apparatus includes at least one motor, an inverter configured to supply power to the at least one motor and a plurality of switching elements configured to convert input DC power into three-phase AC power and output the three-phase AC power, and at least one processor configured to control the plurality of switching elements. The at least one processor is configured to generate a carrier, configured to obtain a rising edge timing and a falling edge timing of a pulse width modulation (PWM) control signal of each phase based on superposition of a zero phase voltage having a predetermined magnitude and the carrier, and configured to drive a motor by shifting the PWM control signal of each phase to allow a rising edge timing and a falling edge timing of a PWM control signal of one phase among the PWM control signal of the each phase to be different from a rising edge timing and a falling edge timing of a PWM control signal of other phase among the PWM control signal of the each phase.
