This part of IEC 61800 applies to adjustable speed electric DC power drive systems, which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the DC motors. It applies to adjustable speed electric power drive systems intended to feed DC motors from a BDM/CDM connected to line-to-line voltages up to and including 1 kV AC 50 Hz or 60 Hz and/or voltages up to and including 1,5 kV DC input side. NOTE 1 Adjustable speed electric AC power drive systems intended to feed AC motors are covered by IEC 61800-2. NOTE 2 This document can be used as a reference for adjustable speed electric power drive systems, intended to feed DC motors from a BDM/CDM connected to line-to-line voltages up to and including 1,5 kV AC, 50 Hz or 60 Hz and/or voltages up to and including 2,25 kV DC input side. Traction applications and electric vehicles are excluded from the scope of this document. This document is intended to define the following aspects of a DC power drive system (PDS): – principal parts of the PDS; – ratings and performance; – specifications for the environment in which the PDS is intended to be installed and operated; – other specifications which might be applicable when specifying a complete PDS. This document provides minimum requirements, which may be used for the development of a specification between customer and manufacturer. Compliance with this document is possible only when each topic of this document is individually specified by the customer developing specifications or by product standard committees developing product standards. For some aspects which are covered by specific PDS product standards in the IEC 61800 series, this document provides a short introduction and reference to detailed requirements in these product standards.
