Solar energy supply system for induction motors and various loads

The authors consider end-user energy transformation in standby solar energy power plants and analyze various possible solutions for utilizing the energy stored in the battery to supply electrical motors, lights, etc. The conversion efficiency and the reliability of the whole system are among the parameters selected to define the optimum system design. Both solar and wind energy conversion technologies and end-user energy transformation are efficiency-dependent. The results obtained based on a lossless step-up chopper and six-step inverter seem to be very attractive from the efficiency point of view and also with regard to ruggedness and reliability, very important quality factors owing to the probable locations of the systems under examination
