THYRISTOR VALVES FOR HIGH VOLTAGE
DIRECT CURRENT (HVDC) POWER TRANSMISSION –
Part 2: Terminology
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60700-2 has been prepared by subcommittee 22F: Power
electronics for electrical transmission and distribution systems, of IEC technical committee 22:
Power electronic systems and equipment.
The text of this standard is based on the following documents:

4 General terms related to converter circuits
4.1
converter arm
part of a bridge connecting two points of different potentials within a bridge, for example
between an AC terminal and a DC terminal
Note 1 to entry: The main function of a converter arm is conversion.
4.2
converter bridge
equipment used to implement the bridge converter connection, if used
SEE: Figure 1
Note 1 to entry: The term "bridge" may be used to describe either the circuit connection or the equipment
implementing that circuit.
[SOURCE: IEC 60633: 2015, 6.2, modified – The expression "and the by-pass arm" has been
deleted from the definition.]
4.3
converter unit
indivisible operative unit comprising all equipment between the point of common coupling on
the AC side and the point of common coupling on the DC side, essentially one or more
converter bridges, together with one or more converter transformers, converter unit control
equipment, essential protective and switching devices and auxiliaries, if any, used for
conversion
SEE: Figure 1
Note 1 to entry: If a converter unit comprises two converter bridges with a phase displacement of 30 degrees,
then the converter unit forms a 12-pulse unit.
5 Converter performance
5.1
forward direction
conducting direction
direction of current through a valve, when current flows from the anode terminal to the
cathode terminal
5.2
reverse direction
non-conducting direction
direction of current through a valve, when current flows from the cathode terminal to the
anode terminal
6 Thyristor valve design
6.1
thyristor
bi-stable semiconductor device comprising three or more junctions which can be switched
from the off-state to the on-state
Note 1 to entry: Devices having only three layers but having switching characteristics similar to those of four-
layers devices may also be called thyristors.
Note 2 to entry: The term "thyristor" is used as a generic term to cover the whole range of PNPN type devices. It
may be used by itself for any member of the thyristor family when such use does not result in ambiguity or
---------------------- Page: 12 ----------------------

misunderstanding. In particular, the term "thyristor" is widely used for reverse blocking triode thyristor, formerly
called "silicon controlled rectifier”.
Note 3 to entry: Thyristors may either be electrically triggered thyristor (ETT） or light triggered thyristor (LTT).
6.2
electrically triggered thyristor
ETT
thyristor triggered by applying electrical pulses to the thyristor gate
Note 1 to entry: This note applies to the French language only.
6.3
light triggered thyristor

area
Note 1 to entry: This note applies to the French language only.
6.4

capacitor connected in parallel to a thyristor (usually in series with a resistor) to reduce the
amplitude of the extinction overshoot voltage
6.4.2

resistor connected in parallel to a thyristor (in series with a capacitor) to limit the amplitude of
discharge current of the snubber capacitor after thyristor turn-on
6.5
DC grading resistor
resistor connected in parallel to the thyristor to equalize DC voltage unbalance caused by
tolerances of thyristor blocking currents
Note 1 to entry: In some designs, DC grading resistor also acts as high voltage arm of the voltage divider for
monitoring voltage across the thyristor level.
6.6
heat sink
separable cooling element, usually through which a heat transfer agent flows, that contributes
to the dissipation of the heat produced within the thyristors and other components, if any, in
the valve
6.7
thyristor control unit
TCU
electronic unit at thyristor level potential used to trigger, protect and monitor the thyristor
Note 1 to entry: Some other terms are used for this unit: thyristor electronics (TE), thyristor firing and monitoring
unit (TFM) or ( thyristor) gating unit.
Note 2 to entry: In some designs, a thyristor voltage monitoring unit (TVM) is used which performs monitoring functions only.
