This paper presents a successful automatic voltage regulation of high-efficiency interior permanent-magnet (IPM) synchronous generators for pico-hydro power generation system. A 1-kW 4-pole V-type IPM generator with low voltage regulation is used for laboratory test in stand-alone hydro energy conversion system. It has been found from experimental results that the constant output voltage is supplied...
This paper presents a successful design of a high-efficiency interior permanent-magnet generator which keeps terminal voltage constant from no load to rated load under a constant speed. This means the generator does not need the voltage control due to the voltage drop associated with the increase in load. Time-stepping finite-element analysis has been used to successfully predict the electromotive...
This paper presents a novel single-phase reluctance generator with low-cost ferrite magnets between adjacent stator teeth. The stator has both 4-pole field and 8-pole armature windings. The armature windings are connected to the input terminals of a single-phase full-bridge rectifier circuit as AC power source. The DC output terminals are connected to the field windings to increase the excited flux...
