Objective To investigate the super capacitor in the elevator energy saving prospect. Method for selecting reasonable elevator energy- saving system structure, in the calculation of the completion of the lift operation in demand power and can lift a single direction one- way operation feedback based on maximum energy absorption, presents the design method of super capacitor. The results of the general inverter Simulink simulation analysis for traction machine, no-load, from no-load to electric state and from no-load to state three cases are g^ven based on the super capacitor energy saving elevator system control strategy, thereby enabling the super capacitor can realize the emergency power supply and energy buffering function and get higher charge-discharge efficiency. Conclusion this study shows, the super capacitor in high power electrical and electronic products especially in elevator products has good application effect and advantage, the application prospect of unlimited.
