摘要

A novel regenerative brake system in electric hoist is proposed and a PSIM hoist simulation model is established in this paper. A PI closed-loop control strategy has been used for regulating the duty cycle of SPWM, in order to control the signal of the DC/DC converter and the charge-discharge current of the ultracapacitor. The no-load experiment on the characteristics of the ultracapacitor has been carried out. On this basis, an ultracapacitor system for an electric hoist is implemented. The efficiency of energy recuperation was 65% at a 10A chargedischarge current of ultracapacitor.
