Title:
CURRENT SOURCE INVERTER AND CONTROL METHOD THEREFOR, COMPRESSOR AND HOUSEHOLD APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2024/000488
Kind Code:
A1
Abstract:
Disclosed are a current source inverter and a control method therefor, a compressor and a household appliance. The current source inverter comprises a three-phase inverter bridge and a zero-current switch, wherein a bridge arm of each phase of the three-phase inverter bridge comprises an upper bridge bidirectional switch tube and a lower bridge bidirectional switch tube; and the zero-current switch is connected in parallel between direct-current buses of the three-phase inverter bridge. The method comprises: before a commutation moment arrives, firstly controlling bidirectional switch tubes corresponding to a first non-zero vector before commutation to be both in a reverse blocking state, and then controlling a zero-current switch to be in a turn-on state; and when the commutation moment arrives, firstly controlling bidirectional switch tubes corresponding to a second non-zero vector after commutation to be both in the reverse blocking state so as to perform commutation, then controlling the zero-current switch to be in a turn-off state, and finally controlling the bidirectional switch tubes corresponding to the second non-zero vector to be both in the turn-on state.
