Fuzzy based bidirectional converter for elevator system with supercapacitor

The dissipation of the energy regenerated by the motor is the primary source of energy waste in elevators. Extra energy created in various ways must be stored for a period of time in order to be used later for the efficient operation of an elevator. An energy storage system is now prevalent in appli...
