Theoretical and experimental analyses of a hybrid excitation synchronous generator with integrated brushless excitation

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.
