Abstract
PURPOSE: To secure the normal operation of the converter through detachment of the faulty gate pulse amplifier from the module by giving a short circuit to the power supply input for the converter for the high voltage use based on the overvoltage of the power circuit in the gate pulse amplifier.
CONSTITUTION: One arm of the converter is formed by connecting m-units of module M composed by connecting SCR1∼SCRn in series. Gate pulse amplifier 1 is provided to each module in the form of the double system with addition of power circuit 2 and pulse amplifier circuit 3. Circuit 3 supplies the gate signal to each SCR by the control signal given from light guide 9. In case the overvoltage is caused to circuit 2 due to the fault of amplifier 1 and the voltage exceeds the fixed amount, the value of nonlinear resistance 15 decreases suddenly. As a result, realy 16 functions to close contact 17, and then the input of rectifier circuit 14 is short-circuited. In such way, faulty amplifier 1 is detached from the module.
