46、trollable semiconductor switch device which can be used in VSC converters for HVDC. For convenience, the term IGBT is used throughout this standard to refer to the main, controllable, semiconductor switch device. However, the standard is equally applicable to other types of controllable semiconducto
47、r switch device. 3.2.1 insulated gate bipolar transistor IGBT a controllable switch with the capability to turn-on and turn-off a load current An IGBT has three terminals: a gate terminal (G) and two load terminals emitter (E) and collector (C). By applying appropriate gate to emitter voltages, the
48、load current can be controlled, i.e. turned on and turned off. 3.2.2 free-wheeling diode FWD power semiconductor device with diode characteristic A FWD has two terminals: an anode (A) and a cathode (K). The current through FWDs is in the opposite direction to the IGBT current. FWDs are characterized
49、 by the capability to cope with high rates of decrease of current caused by the switching behaviour of the IGBT. 3.2.3 IGBT-diode pair arrangement of IGBT and FWD connected in inverse parallel 3.3 Operating states 3.3.1 Operating state of an IGBT-diode pair 3.3.1.1 blocking state the condition in which an IGBT-diode pair is turned off In that state, the load current does not flow through the IGBT.
