5.3 EMC information
General information about converters
Modern semiconductor technologies such as MCTs and IGBTs are intended to minimize the power loss
in the converter by switching more quickly and, with this, to continually reduce the size of the power sec-
tion. As a result, when running converters you must meet specific conditions to avoid electromagnetic
influences caused by switching operations.
Disturbances can occur due to:
y capacitive fault currents caused by high rates of voltage rise when bipolar transistors and IGBTs
switch.
y high currents and high rates of current rise in the motor lines. The disturbance energy bound in mag-
netic fields reaches frequencies of between a few Hertz and about 30 MHz. Due to the high rates of
current rise, additional electromagnetic fields occur with frequencies of up to approximately 600
MHz.
y high clock rates and fast logic circuits (electromagnetic field/16 MHz...1 GHz).
y system perturbation and harmonics caused by commutations and non-sinusoidal network loading,
in particular with line-commutated converters (100 Hz ... 20 kHz).
German EMC Law (EMVG)
This converter complies with Paragraph 5, Section 5, Sentence 3 of the German EMC Law (EMVG) dat-
ed 09.11.92.
"Devices that are exclusively manufactured or stocked as vendor parts or spare parts for further process-
ing by industrial companies or craftsmen or by other specialists in the field of electromagnetic compati-
bility do not need to comply with the protective requirements of Paragraph 4, Section 1, nor do they need
EU conformity certification and marking, assuming that the devices in question cannot be run automati-
cally."
This does justice to the fact that EMC is heavily dependent on the individual subassemblies and compo-
nents in the switching cabinet. With regard to the total costs of the machine, it is preferable to trouble-
shoot an entire system rather than each of its individual components.
The information on the next few pages is intended to allow you to configure your system on the basis of
the latest knowledge in the field of EMC and to comply with legal regulations.
