摘要
能量回馈技术是曳引式电梯节能的主要方式,介绍了能量回馈技术的节能原理和发展情况,重点分析了普通晶闸管能量回馈系统、PWM控制通用变频器能量回馈系统和正弦波脉宽调制双PWM控制技术的应用情况,最后提出能量回馈技术今后的发展趋势。
The energy regeneration technology is the uppermost method to save energy in traction elevators.The energy saving theory of energy regeneration technology and its development are introduced in this paper.Then,the Thyristor-controlling energy regeneration system,the PWM controlling energy regeneration system and the sine-wave pulse-width modulation twin-PWM controlling technology for common frequency converter are discussed.At last,the direction of the energy regeneration technology is also put forward.
