Air conditioner and inverter driving circuit therefor |
摘要 |
In an inverter driving circuit and an air conditioner having the same, the circuit elements constituting the inverter driving circuit are arranged and connected through wirings along a power supply path so that those circuit elements and wirings which are located at the front stage of a noise filter are spatially separated from those circuit elements and wirings which are located at the rear stage of the noise filter. A power source of a controller for the inverter driving circuit is supplied with an alternating power from a neutral point and one of three phases (R,S,T) of the noise filter, and a high-frequency noise occurring in a transistor module is intercepted by a smoothing circuit and a rectifying circuit, so that the noise contamination into the controller can be prevented. The voltage to be supplied to the controller may be a low voltage.
