The invention discloses an elevator system. During normal operation, alternating current mains supply is converted into a first direct current voltage by a control power converter to supply power to an elevator control unit; when the alternating current mains supply is powered off, the direct current voltage on a super capacitor is converted into a second direct current voltage by a first power converter to supply power to the elevator control unit; an elevator can still operate normally without emergency stop, so as to provide a comfortable elevator taking experience for passengers, and no psychological tension and anxiety are caused to the passengers due to power failure; and the super capacitor is used as the only energy storage component, and no storage battery is configured for emergency power supply, thereby improving the integration level and equipment utilization rate of the elevator, and improving the cost performance of using the super capacitor in the elevator.

    本发明公开了一种电梯系统,在正常运行时,由控制电源转换器将交流市电转换为第一直流电压为电梯控制部供电;在交流市电断电时,通过第一电源转换器将超级电容上的直流电压转换为第二直流电压为电梯控制部供电,电梯仍能正常运行不发生急停,给乘客舒适的乘梯体验,也不会因为停电造成乘客心理上的紧张和不安,将超级电容作为唯一的储能元件,不再配置蓄电池以应急供电,提高了电梯的集成度和设备利用率,提高了在电梯中使用超级电容的性价比。
