Abstract

For the analysis of transient zero through the thyristor turn-off characteristics of recovery factors, the researchers are by changing the polarity of the supply voltage of the anode current commutation always realize thyristor is turned off, but will be under a lot of anti-off thyristor during recovery forward voltage, and this paper was forced commutation thyristor zero crossing, after the zero-crossing through the freewheeling diode voltage across the thyristor is zero, so the previous studies are not suitable for the object of this article. This paper presents the experimental circuit thyristor forced through zero-zero-voltage shutdown recovery by the experimental system to study the effects of the thyristor transient recovery time of two important factors, and in respect of factors (the size of the through-flow, flow time) thyristor recovery time characteristics of the particular what impact do a detailed analysis and the results showed that: the thyristor through-flow growth and an increase in the magnitude of flow-through time will adversely affect their recovery time
