| Post subject: thyristor converters |
I need a good tutorial website for thyristory-based commutators (rectifiers+inverters) ,thyristor voltage and current regulators,frequency converters (from DC to AC) and such things. There are also thyristor converters as single phase or three phase,as single set or dual set of thyristors.Those might be included at comanies sites but i don't know how to get them so please help me. |

i mean to say.. if u get information regarding designing of thyristor convertor which u wanted please let me also know.today i saw the manual of siemens AC drive in which some design aspects were given but i couldnt bring it bcoz its office documents.. |

There are many pulse systems differ by changing firing angles between the set itself and also between the two sets(rectifier+inverter) but i think that the most useful practical way is "seperate control" which depends on sending pulses to one set and removing pulses from the other sequentially....
I need help concerning PSR and PSI cause all that i know is the chart symbols for each of them so i need the real practical circuit used in such cases.
where VA,VB,Vc are 120 phase-shifted of each other. |
