Abstract

A study is presented of the optimal operating parameters of a system comprising a photovoltaic solar array and a DC electromechanical energy converter (motor) driving a mechanical load. The analysis and design procedure includes the addition of a variable DC-DC matching transformer placed between the array and the motor. It is responsible for adjusting the load curve seen by the array to coincide with its maximum power point. The model takes into consideration the effect of different temperature as well as isolation profiles along the year. The analysis procedure guides the design of DC motors as well as variable DC transformers especially suited to be operated in conjunction with PV arrays. The procedure determines optimal motor constants which lead to an improved overall design in terms of maximizing the total annual gross mechanical energy delivered to a load of a given torque-speed characteristic
