Title:
NON-HIGH SIDE POWER TUBE INVERTER CIRCUIT AND INVERTER MODULE
Document Type and Number:
WIPO Patent Application WO/2023/217259
Kind Code:
A1
Abstract:
A non-high side power tube inverter circuit and an inverter module, which relate to electronic technology. The inverter circuit in the present invention is connected to become an annular structure by at least two inverter modules. The inverter module comprises: a pre-filter circuit, which has a signal input end and a signal output end, wherein the signal input end thereof serves as a modulation signal input end; a middle filter circuit, which has a direct-current power input end and an alternating-current power output coil, wherein a signal input end of the middle filter circuit is connected to the signal output end of the pre-filter circuit; and a signal output circuit, wherein a signal input end thereof is connected to the signal output end of the middle filter circuit, and a signal output end thereof serves as a modulation signal output end. In the present invention, the cost of an inverter can be significantly reduced, a controller algorithm can be simplified, and when the present invention is applied to a battery power vehicle, the requirements of the battery power vehicle for a battery management system can be reduced, such that the cost of the vehicle is reduced.
