The Design and Optimization of a Novel Hybrid Excitation Generator for Vehicles
World Electric Vehicle JournalSilicon rectifier generators, which are single-excitation generators, are commonly used in vehicles. However, a traditional single-excitation generator cannot satisfy the requirements of modern vehicles due to its low efficiency, high failure rate and ...

IET Electric Power Applications, 2016 This paper proposes a novel integrated brushless excitation method (IBEM) for a rotor‐excited generator. IBEM is applied to a rotor‐excited hybrid excitation synchronous generator (HESG) to realise brushless excitation while the key features of the rotor‐excited generator are maintained. The new generator is referred as IBE HESG here.

A Consequent-Pole Hybrid Exciter for Synchronous Generators [PDF]
IEEE Transactions on Energy Conversion, 2021 In low-to-medium power generating sets, a self-powered brushless excitation system is typically employed. This solution is cost-effective, simple and compact, but it suffers from an unreliable voltage build-up at start-up, a slow dynamic response and a relatively low efficiency for the exciter.
