Claw-Pole Alternators with Hybrid Excitation - A Brief Review

This paper focuses on reviewing the existing concepts for designing a hybrid excited claw-pole alternator. This type of electrical generator is relatively easy to produce and is relatively cheap, and the use of hybrid excitation consisting of permanent magnets and excitation winding helps reduce the losses in the machine and facilitate the operation, by eliminating the power electronic converters required to regulate the output voltage. The review is based on more than 40 literature sources from recent years and explores the tendencies in the design of hybrid alternators.
