Flow type hoisting machinery power device utilizing accumulator

A flow type crane mechanic power device using energy storage has source power connected to the rectifier device, flowing device connecting energy consumption resistance through direct current bus, energy consumption resistance reconnecting inverter connecting to the working generator. The stabilizer capacitor connects to the direct current bus, both ends of the stabilizer capacitor connecting to the positive and negative electrodes of the direct current bus. The energy storage connects to the dual directional DC/DC converter, which connects in parallel to the bus stabilizer capacitor. It adopts various source power device, using energy storage at the same time, being able to recover regenerated energy feedback by all working mechanism to act as working energy, saving energy source, reducing impact due to recovery energy feedback, realizing zero emission and noise with reduced overall capacitor.
