Title:
AC GENERATOR
Document Type and Number:
WIPO Patent Application WO/2013/139060
Kind Code:
A1
Abstract:
An AC generator, comprising an engine (1) serving as a power source, two multi-pole high-frequency generators (M1, M2) having different numbers of magnetic poles, a commutation conductive ring (5), a carbon brush (6) and a rectifier circuit; the rotors of the two multi-pole high-frequency generators (M1, M2) are installed on the same rotor shaft (2) driven by the engine (1); the rotor coils of the two multi-pole high-frequency generators (M1, M2) are connected in series and are then connected to the input terminal of the rectifier circuit; the output terminal of the rectifier circuit is connected to the commutation conducting ring (5) also installed on the rotor shaft (2); and the commutation conducting ring (5) is in contact with the carbon brush (6) and outputs the required sinusoidal wave alternating current. The AC generator has a simple structure and a convenient production process, saves a great amount of silicon steel material and copper material, thus reducing cost, having a high power generating efficiency, and generating the sinusoidal wave alternating current having little waveform distortion and strong anti-interference capability.
