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...

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 applications for energy conservation and traction. This research proposed to design an elevator system with a supercapacitor (energy storage) controlled by fuzzy based bidirectional DC-DC converter. The supercapacitor is used to store the regenerated energy from the motor during braking mode and releases the stored energy during motoring mode. The bidirectional DC-DC converter controls the power flow to the elevator motor, power supply, and supercapacitor bank. The system introduced two fuzzy-logic controllers for voltage and current which to provide a control to bidirectional DC-DC converter in storing and recovering the energy from supercapacitor. The purpose of this research is to analyze the performance of bidirectional DC-DC converter with fuzzy logic controller in optimizing the generated energy into supercapacitor during the operation of the elevator system. Based on the simulation result, with the present of supercapacitor in elevator system, the energy from the motor during generating mode will not be wasted. The energy stored in supercapacitor and can be use during motoring mode. |
