DD IEC/TS 61800-8:2010

This standard DD IEC/TS 61800-8:2010 Adjustable speed electrical power drive systems is classified in these ICS categories:

• 29.200 Rectifiers. Converters. Stabilized power supply
• 29.160.30 Motors

This part of IEC 61800 gives the guidelines for the determination of voltage on the power interface of power drive systems (PDS’s).

NOTE The power interface, as defined in the IEC 61800 series, is the electrical connection used for the transmission of the electrical power between the converter and the motor(s) of the PDS.

The guidelines are established for the determination of the phase to phase voltages and the phase to ground voltages at the converter and at the motor terminals.

These guidelines are limited in the first issue of this document to the following topologies with three phase output

• indirect converter of the voltage source type, with single phase diode rectifier as line side converter;

• indirect converter of the voltage source type, with three phase diode rectifier as line side converter;

• indirect converter of the voltage source type, with three phase active line side converter.

All specified inverters in this issue are of the pulse width modulation type, where the individual output voltage pulses are varied according to the actual demand of voltage versus time integral.

Other topologies are excluded of the scope of this International Specification.

Safety aspects are excluded from this Specification and are stated in IEC 61800-5 series. EMC aspects are excluded from this Specification and are stated in IEC 61800-3.
