Title: Control of thyristors d.c. converters
IPC: H02M3/139
Filed: 1978-06-27
Abstract: In the control of an m-phase thyristor pulse d.c. converter for use e.g. in electric traction and in stationary d.c. electric drives, the conductive duration and the onset of conduction of the thyristors are controlled in dependence upon time- shifted and time-constant pulse trains. A number of control channels each have a control zone within the overall control range of the system and each control channel is arranged to switch in succession between control of the m thyristor outputs as its control zone for any one thyristor is exhausted. A counter 2 driven by a master oscillator 1 supplies pulse inputs to m decoder networks 3-6 which each receive a further input from a control unit (bidirectional counter 9) and provide an output in response to their two inputs having particular related values, the decoder networks feeding a logic network 14 of AND gates to selectively cyclically permute the connections from the decoder networks, these carrying the time- shifted pulse trains to turn off the thyristors. A decoder network 7 responsive to counter 2 provides the time-constant pulse trains to turn on the thyristors. <IMAGE>
