Introduction was made to industrial frequency conversion energy feedback technologies in common use in the process of motor braking under the system of industrial variable frequency electric drive at present. This paper discussed the principle, energy- saving effect and applications of various energy feedback technologies, including universal PWM inverter energy feedback techno- logy, common DC bus technology, super-capacitor technology and dual-PWM inverter energy feedback technology. The result shows that the inverter energy feedback technology more widely applied in industrial variable frequency electric drive systems is the new development trend of the variable frequency speed control.
