Title:
SINGLE-STAGE THREE-PHASE POWER CONVERSION DEVICE AND POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/133015
Kind Code:
A1
Abstract:
A single-stage three-phase power conversion device and a power transmission device. The conversion device comprises a three-phase rectification and commutation module (301) and a DC/DC conversion module (302). The three-phase rectification and commutation module has a three-phase AC connection end, a DC source first connection end (3011), a DC source second connection end (3012) and a DC source third connection end (3013). The DC/DC conversion module has a first connection end (3021), a second connection end (3022), a third connection end (3023), a DC source positive connection end and a DC source negative connection end. A three-phase AC source is connected to the three-phase AC connection end of the three-phase rectification and commutation module (301). The DC source first connection end (3011) of the three-phase rectification and commutation module (301) is connected to the first connection end (3021) of the DC/DC conversion module, the DC source second connection end (3012) is connected to the second connection end (3022) of the DC/DC conversion module, and the DC source third connection end (3013) is connected to the third connection end (3023) of the DC/DC conversion module. A positive terminal of a DC source is connected to the DC source positive connection end of the DC/DC conversion module, and a negative terminal of the DC source is connected to the DC source negative connection end of the DC/DC conversion module. The conversion device reduces the number of control variables involved, and can reduce the complexity of controlling a rectification or commutation of a three-phase power source.
