Double rectifier bridge and double stator automobile generator

Abstract

The invention discloses a double rectifier bridge and double stator automobile generator. The double rectifier bridge and double stator automobile generator comprises rotatable rotors, one annular stator core, two group of stator windings and two rectifier bridges, wherein the rotatable rotors can be used for providing a rotating field; each group of stator winding is twined around part of the stator core to form a stator, and magnetic circuits corresponding to the two stators are not overlapped mutually, and each group of stator winding can generate AC voltage according to the rotating field; each rectifier bridge is connected with the output end of the group of stator winding to convert the induced AC voltage in the stator winding into DC voltage; and the two rectifier bridges are connected in parallel so that the DC voltage of the two rectifier bridges are output in parallel. The double rectifier bridge and double stator automobile generator can reduce the rectified voltage ripple so as to improve the output capability of the generator and reduce the interference of the generator to electric equipment of a finished vehicle.

Description

technical field [0001] The invention relates to the field of generators, in particular to a double rectifier bridge and double stator automobile generator. Background technique [0002] In recent years, automotive electronic appliances have developed rapidly. There are more and more electronic instruments and sensors with various functions in the vehicle. Air conditioners such as high power consumption and electronic retarders have basically become the standard equipment of the vehicle, which greatly improves the The driver's controllability and the safety and comfort of the passengers, but it brings more and more demands on the electricity consumption of the whole vehicle, and the stability and quality requirements of the power supply system (that is, the stability of the voltage , current fluctuations and harmonic components) are getting higher and higher. Therefore, there are more and more applications of high-power generators (output current greater than 100A). Since t...

Problems solved by technology

[0003] The load capacity of the rectifier bridge mainly depends on the rated output capacity of the rectifier. The current rectifier that can be commercialized and widely used can only reach 60A. If the rectifier is at the limit or overloaded, the high current will Cause the temperature of the rectifier tube to rise sharply, so that the rectifier tube will burn out soon
