In the development of science and technology changes with each passing day today, air conditioner and other high-tech products, also with the acceleration of development ac electric motor trend. Motor variable frequency speed regulation technology development and application of frequency conversion air conditioner development has injected new vitality. In 1964, the German put forward PWM inverter technology such as a. Schonung (Pulse Width Modulation). The core component of the speed regulation control technology is inverter, change the dc into frequency adjustable device for alternating current (ac). As the electronic technology, microelectronics technology, the development of the single Three phase motor chip microcomputer control technology, inverter power, increasingly powerful, cost performance is higher and higher.

Sanyo company from 1974 to start producing frequency conversion air conditioner, the sanyo in Japan in the production of air conditioner, frequency conversion air conditioner production accounts for about 80%. In some developed countries, frequency conversion air conditioning's penetration in the domestic has reached 60%. Frequency conversion air conditioning brands abroad mainly Japanese sanyo, panasonic, Hitachi, daikin, sharp, etc. Domestic frequency conversion air conditioning mainly hisense, haier, midea, gree brand, etc. Because of the complexity of generator set the frequency conversion air conditioner, in learning, frequency conversion air conditioner maintenance knowledge before we start to understand the working principle and characteristics of frequency conversion air conditioner, in a later article focuses on the characteristics of the frequency conversion air conditioner circuit, system and maintenance methods.
