基手DSP的交流提升机减速及爬行段速度控制变流电源的研究

Current - variable power source of speed control in decelebration and low speed drive period of AC shaft hoist base on DSP

论述了交流提升机减速及爬行段对速度的要求及目前设备存在的问题,提出了在DSP基础上采用交—直—直变流电源解决动力制动电源,采用交—直—交变频电源解决低速爬行要求,给出系统的结构。

The required of speed in decelebration and low speed drive period of AC shaft hoist, and some problems in equipment are introduced in paper. Persents one new technique by AC - DC - DC current - variable power source resolve the power of dynamic braking, and AC - DC - AC frequency - variable power source resolve the required of low speed drive base on DSP. Describes its structure of system.
