Dynamic properties of hybrid filters in regenerative braking thyristor systems

On the basis of frequency models in orthogonal coordinates /spl alpha/-/spl beta/, properties of sectional hybrid filters were considered in the case of dynamic changes of a distorted load current. Results of transient process testing when switching on and off respective sections were described. On this basis, taking into consideration earlier testing results in steady states, a full suitability evaluation of presented filtering-compensating hybrid systems solutions concerning a regenerative braking stand has been carried out.
