Title:
POWER FACTOR CORRECTION CIRCUIT AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/232994
Kind Code:
A1
Abstract:
A power factor correction circuit and an air conditioner; the power factor correction circuit comprises: a power factor correction module (10), which receives a power supply signal from an alternating current power supply, the power factor correction module comprising switch transistors; a first reactor and a second reactor, wherein the first reactor is provided on a live wire of the alternating current power supply, and the second reactor is provided on a neutral wire of the alternating current power supply; drive modules (202, 204), which are connected to drive input ends of the switch transistors and which are used for outputting switching signals to the switch transistors; and a control module (30), which is connected to the drive modules (202, 204) and which is used for controlling the drive modules (202, 204) to turn on or turn off the output of switching signals. The first reactor and the second reactor are provided on a live wire and neutral wire of a mains supply; compared to a single reactor circuit, the effect of superimposing two reactors may be achieved, and same can be installed in a power factor correction circuit instead of a large-size reactor that is difficult to assemble, thus reducing the difficulty of installation.
