Along with widely application of the high-power phase control thyristor deflector,in the process of the exploitation and application,the component choose,the power component radiator design,the fan and wind pathing design are very important.

In successful reformation of tinning wire soft melting system in Cold Rolling Works of Wuhan Iron and Steel(Group) Co,high power thyristor unit,full digital control system and PLC were adopted and comprehensive control and regulation of tinning soft melting current,soft melting temperature and strip operation velocity were realized.

This paper introduced on Computer Control heavg duty SCR rectifier unit system,fuction,Characteristic and applied effect in Chlorine alkaline productio

This paper introduces a new type of intelligent digital trigger for large power SCR rectifier unit with the fuzzy self-adjusted PI,as the control law system is based on microcontroller MC9S12DP256B and a digital signal processor (DSP) TMS320LF2407.

For the convenience of operational tests about the high power thyristor valves, a new synthetic test equipment (STE) is presented based on the analysis of the current test technology for high power thyristor valves and the requirements of the IEC Standards for the STE, as well as the topology and operation theory of the STE.
