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.

IEC 60092-304 has been prepared by IEC technical committee 18: Electrical installations of

ships and of mobile and fixed offshore units. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 1980 and
Amendment 1:1995. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) scope limited to converters greater than 1 kW;
b) terms and definitions: essential services added;
c) deleted selenium rectifier;

d) changed service conditions to 6. Effects from and on supply system new text added with

parts from Clause 7 of IEC 60092-304:1980;

e) Clause 7: application changed to converters for essential services construction and

documentation new text added;

f) Clause 8: application added;
g) Clause 9: test added;
The text of this International Standard is based on the following documents:
Draft Report on voting
18/1780/FDIS 18/1782/RVD

Full information on the voting for its approval can be found in the report on voting indicated in

the above table.
The language used for the development of this International Standard is English.

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in

accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available

at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are

described in greater detail at www.iec.ch/standardsdev/publications.

A list of all parts in the IEC 60092 series, published under the general title Electrical installations

in ships, can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under webstore.iec.ch in the data related to the

specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or

INTRODUCTION

IEC 60092 (all parts) forms a series of International Standards for electrical installations in sea-

going ships, incorporating good practice and co-ordinating, as far as possible, existing rules.

These standards form a code of practical interpretation and amplification of the requirements

of the International Convention on Safety of Life at Sea, a guide for future regulations which

may be prepared and a statement of practice for use by shipowners, shipbuilders and

appropriate organizations.

ELECTRICAL INSTALLATIONS IN SHIPS –
Part 304: Equipment – Semiconductor converters
1 Scope

This part of IEC 60092 specifies special provisions to power electronic converters and systems,

using semiconductor elements for use in ships. The conversion may be from AC to DC, from

DC to AC, from DC to DC or from AC to AC with a rated output power greater than 1 kW.

This document does not apply to semiconductor converters used in electrical propulsion plant.

For semiconductors converters used in electrical propulsion plant, see IEC 60092-501.
