A flexible electromagnetic interference means HVDC valve for the sub-module controller

The present invention provides an electromagnetic interference means flexible HVDC valve controller for a sub-module, it is a system of electromagnetic interference HVDC flexible design. The lifting means electromagnetic immunity flexible HVDC system submodules, the common good, so that the whole system of the control apparatus of this card can be used, reducing the cost of the entire system. Means for suppressing interference varistors, transient voltage diode (TVS), electrolytic capacitors, X capacitive, common mode inductance devices such targeted selection, so that the parameters match, then concentrated encapsulated in a module, module left two input, two output ports. The apparatus of the present invention focus on a variety of devices in a module package, a reasonable match parameters, the total volume of small, highly integrated, reliable; can be applied to various circuits on the power input board, directly welded, installation is very Convenience.
