Selection of energy source depends on several factors, including energy availability, economic and power requirements. Hydro power is more cost effective than any other form of renewable power. This paper studies the performance of various stator designs in a micro hydro generator. The generator generates energy using rainwater that falls from the roof drainage system. The rainwater flows through...
In this paper, a radiation model of Magnetic Flux Compression Generator with capacitive load is proposed based on the electrically small loop antenna theory, which can help to predicting the radiation characteristics of Magnetic Flux Compression Generator with capacitive loads and providing the necessary guidance on performance improvement and their experiment. The approximate calculation is necessary,...
In this paper we introduce an approach for solving the state equations of a helical flux compression generators. These state equations are obtained from 2-dimensional filamentary model of helical flux compression generators. Firstly, we derivate the matrix representation of differential equations of the heliacal flux compression generator. Then with selection of the appropriate state vector, the state...
In this paper we present an approach to calculate the time varying equivalent inductance and resistance of the helical flux compression generators accurately. This approach is based on the 2-D filamentary method and using dynamic matrix concept. By using this method, we can consider both the effects of the armature presence and frequency on the inductance and resistance of the HFCGs. The latter effect...
This paper describes the design and development of a 5 kW, 150 rpm, air-cored, axial flux generator for use as a direct drive generator with small wind and water turbines. The generator uses trapezoidal shaped magnets to obtain a greater active length than that provided by circular magnets. The armature coils are also trapezoidal. A prototype generator has been tested and produces up to 5000 W at...
