Title:
INVERTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/174807
Kind Code:
A1
Abstract:
Disclosed is an inverter system, comprising a dual three-phase electric motor, a first current sensor, a second current sensor, an electric motor control module, and a plurality of inverters arranged in parallel, wherein the plurality of inverters comprise a first inverter and a second inverter, and the first inverter and the second inverter are both configured to convert electrical energy from a direct current into an alternating current; the dual three-phase electric motor is configured to receive the alternating currents converted by the first inverter and the second inverter, so as to be driven; the first current sensor is configured to measure a first current output by a corresponding output end of the first inverter; the second current sensor is configured to measure a second current output by a corresponding output end of the second inverter; and the electric motor control module is configured to send a driving signal to the plurality of inverters according to the first current and the second current.
