With the increasing concerns on more electricity or full electricity for modern energy
conversion systems, the key component of electric machine, has been paid more and more …

Hybrid excited synchronous machines (HESMs) combine permanent-magnet (PM) excitation
and wound field (WF) excitation. The goal of hybrid excitation is to combine the advantages …

A new maximum power point tracking technique for permanent magnet synchronous
generator based wind energy conversion systems is proposed. The technique searches for …

This paper proposes a new outer-rotor permanent-magnet (PM) vernier machine for direct-
drive wind power generation, which can offer low-speed operation to directly capture wind …

With ever-increasing concerns on energy issues, the development of renewable energy
sources is becoming more and more attractive. This paper first reviews both the wind power …

A new permanent-magnet (PM) hybrid brushless (PMHB) machine is proposed and
implemented as the integrated starter-generator (ISG) for hybrid electric vehicles (HEVs). It …

This paper gives an overview of various electric machines for application to renewable
energy harvesting, and reveals the corresponding challenges and research opportunities …

By artfully integrating the vernier structure and the DC field winding together, a novel flux-
controllable vernier permanent-magnet (FCVPM) machine is proposed, which has the merits …

This paper presents 3-D finite-element analysis of a new double excitation synchronous
machine. It is shown that the machine has true field regulation capability. The principle of …

This paper presents the design of a high-voltage hybrid generator (HG) and conversion
system for wind turbine applications. The HG combines wound field (WF) and permanent …
