SYSTEM AND METHOD FOR CONTROLLING INVERTER

摘要

A method and system for controlling an inverter for operating a motor are provided. The method includes reducing a switching frequency of the inverter for applying a load current to the motor when the motor is used for energy consumption. Reduction of the switching frequency of the inverter enhances damage prevention and durability of the inverter. In the method, an operation mode of the inverter for operating the motor is determined based on a command received from an upper-level controller. When the operation mode of the inverter is determined to be an energy consumption mode, a switching frequency of the inverter is decreased relative to the switching frequency in a general operation mode.

1. A method for controlling an inverter, the method comprising:
determining, by a first controller, an operation mode of the inverter, based on a command received from an upper-level controller; and decreasing, by the first controller, a switching frequency of the inverter to be less than a frequency of the inverter in a general operation mode, when the operation mode of the inverter is determined to be an energy consumption mode.
