Rectifier, alternator - 139113 HITACHI

The rectifier of the alternator is a device that converts the alternating current, which is produced by the automobile generator, into direct current. The unit is located at the rear of the generator and consists of fins and diodes that pass current in one direction. The device is sensitive to temperature changes and may be susceptible to contamination.

The functionality of the alternator rectifier

An automobile or motorcycle generator performs the function of providing all equipment with electricity. But the generator is capable of producing only alternating current, and it is not suitable for ensuring the operability of electrical equipment. In order to convert alternating current into direct current, a rectifier is mounted at the generator output.

HITACHI brand Rectifier, alternator may differ in their design, but their actions are the same. They can be manufactured and assembled from individual parts or in the form of a block. The first design is cheaper, maintainable, but larger. Monoblock design - compact, but much more expensive to assemble, and in case of failure of one of the diodes, it is necessary to buy and replace the entire generator bridge.
