一种单相矩阵变频器和空调系统
摘要：
本发明实施例公开了一种单相矩阵变频器和空调系统，包括：第一桥臂、第二桥臂、第三桥臂、第四桥臂、第五桥臂、第六桥臂；其中，第一桥臂的第一端与第三桥臂的第一端以及第五桥臂的第一端相连，并连接于单相交流电源的第一端，第一桥臂的第二端与第二桥臂的第一端及空调压缩机的第一端相连；第三桥臂的第二端与第四桥臂的第一端及空调压缩机的第二端相连；第五桥臂的第二端与第六桥臂的第一端及空调压缩机的第三端相连；第二桥臂的第二端与第四桥臂的第二端以及第六桥臂的第二端相连，并连接于单相交流电源的第二端。该系统采用交‑交变换，杜绝了直流环节所带来的谐波污染及无功功率，提高了功率密度。
摘要（英）：

The invention discloses a single-phase matrix frequency converter and air conditioner system. The single-phase matrix frequency converter and air conditioner system comprises a first bridge arm, a second bridge arm, a third bridge arm, a fourth bridge arm, a fifth bridge arm, and a sixth bridge arm. The first end of the first bridge arm is connected with the first end of the third bridge arm and the first end of the fifth bridge arm, and is connected with a first end of a single-phase AC power supply. The second end of the first bridge arm is connected with the first end of the second bridge arm and a first end of an air condition compressor. The second end of the third bridge arm is connected with the first end of the fourth bridge arm and the second end of the air condition compressor. The second end of the fifth bridge arm is connected with the first end of the sixth bridge arm and the third end of the air condition compressor. The second end of the second bridge arm is connected with the second end of the fourth bridge arm and the second end of the sixth bridge arm, and is connected with the second end of the single-phase AC power supply. The single-phase matrix frequency converter and air conditioner system is advantageous in that by adopting the AC-AC conversion, the harmonic pollution and the reactive power caused by the DC link can be prevented, and the power density can be improved.
