Abstract：
 A minimum time controller for the compensation of controllable series capacity features as using upper level controller of upper position target trigger angle in operation control computer as the input, using synchronous signal generating circuit of linear current as the input, using synchronuos signal generating circuit of linear current as the input, using the linear current synchronous signal coming separately from actual trigger angle of upper level controllor and from synchronous signal generating circuit as the input and using the pulse generator of thyristor trigger pulse as the output. The upper level controllor includes the controller being connected with operation control computer, the dual entrance RAM and bus buffer being connected each to controllor, the digital signal processor with EERPOM and SRAM to be connected with dual entrance RAM, bus buffer and A/D digital collecting card separately. The iterative method has been applied for the control caculation of actual trigger angle in thyristor correspondingly. The present invention only has the active state responding time of loms as almost near the extreme for the system going to the stable state immediately after the saltus.
