Small-capacity generators are demand for electric sources in portable sources driven by engines. Therefore, the construction of the generator required simple and robust. It is desirable to make synchronous generators brushless from the viewpoints of easy maintenance and high reliability. Permanent-magnet generators are brushless type, there is an obvious advantage in the use of permanent-magnet, in that the field winding and d. c. supply source are not required<BR>In PM generators, the voltage regulations become large in their over load conditions, because the magnet field cannot be controlled. It is preferable that the voltage regulation of generators has a small numerical value. The purpose of the subjective study is to decrease the voltage regulation of the PM genarator. This paper presents a demonstration of the PM genarator with capacitors.<BR>The armature winding of the PM generator flows lead current because of its capacitors. Then, the armature reaction of the PM generator has magnetization effect because of its capacitors. Therefore, the voltage regulation of the PM generator is small value due to the capacitors. The load characteristics are calculated using an equivalent circuit of the PM generator with capacitors. The analysis has been extended to cover the efect of various parameters on the generator characteristics. The PM generator with capacitors has a voltage compensation function. The aim of research is to provide some outlines for design.
