TLDR
In this article, a new method for optimum matching of an electric motor, with a varying mechanical load, to a solar cell array (SCA), is presented, which enables, by means of switching procedures of the SCA together with flux changes, to assure maximum mechanical energy supply to the load.Abstract:
The increased use of solar electrical (photovoltaic) systems, especially solar power packs for water pumpting, etc., brings about the need for a new approach for analysis and design. In this paper a new method for optimum matching of an electric motor, with a varying mechanical load, to a solar cell array (SCA), is presented. This method enables, by means of switching procedures of the SCA together with flux changes, to assure maximum mechanical energy supply to the load. Moreover, the use of the DCT enables to overcome the problem of the relatively large starting currents of the motor.read more
