WIPO Patent Application WO/2019/033478
Kind Code:
A1
Abstract:
A multi-inverter motor controller, comprising a primary inverter (102) and a secondary inverter (103). The primary inverter (102) and the secondary inverter (103) are connected in parallel to the same motor (104). The primary inverter (102) uses a silicon material power electronic component. The secondary inverter (103) uses a wide-band-gap power electronic component. The switching frequency of the primary inverter (102) is less than that of the secondary inverter (103). The invention improves motor efficiency and reduces vibration noise.
