Title:
RECTIFICATION DEVICE AND ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2017034741
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rectification device capable of preventing dielectric breakdown further than the prior arts while suppressing a physical constitution small, and a rotary electric machine.SOLUTION: In a rectification device 20, a pair of brushes 23 (namely, a positive pole brush 23a and a negative pole brush 23b) are connected with a power source E, and a pair of rectification brushes 21 (namely, rectification brushes 21a and 21b) are disposed at a rear side of the brushes 23 in a rotation direction AR of a rectifier 22. The rectification device comprises diodes D that are connected mutually between the pair of rectification brushes 21. In such a configuration, the number of diodes D can be reduced, and the number of conducting lines may also be reduced. Therefore, a physical constitution of the rectification device 20 can be suppressed small. A rectifier piece 22a may become a voltage that is changed just by a voltage drop of the diode D electrically connected mutually between the pair of rectification brushes 21a and 21b, and a potential difference from the power source is made less than a dielectric breakdown voltage. Thus, the dielectric breakdown may be prevented further than the prior arts.SELECTED DRAWING: Figure 2
