Frequency converter<br />
with DC supply. SIEB & MEYER has<br />
applied for NRTL/CSA certification<br />
for all device variants so that users<br />
can soon integrate the devices into<br />
machines for the US market without<br />
additional approvals.<br />
Advantages of multilevel<br />
technology at a glance:<br />
Fig. 6: Innovative applications that were developed due to the German turnaround in energy<br />
policy also benefit greatly from multilevel technology. SD4M ensures, for example, a significant<br />
increase in the efficiency of regenerative systems such as rotating energy storage units<br />
(flywheel).<br />
Operation of high-speed motors<br />
with<br />
– very good current quality<br />
– low power loss<br />
– low rotor heating<br />
– high system efficiency<br />
– low insulation stress and<br />
– reduced CO 2<br />
emissions<br />
of the motor cable, the amplitude<br />
of the voltage jumps causes this effect.<br />
Three-level converters use only<br />
50 % of the voltage amplitude at each<br />
switching operation, reducing the<br />
partial discharge problem even with<br />
longer motor cables to a great extent.<br />
Therefore, the effect can be neglected<br />
in the most cases.<br />
What does the SD4M series<br />
by SIEB & MEYER offer?<br />
For the development of the SD4M series,<br />
SIEB & MEYER combined tried and<br />
tested technology with the latest control<br />
and communication technology.<br />
The three-level technolo gy of SD4M<br />
combined with device-dependent<br />
switching frequencies of up to 32 kHz<br />
ensures excellent current quality,<br />
which reduces motor losses and increases<br />
the efficiency accordingly.<br />
The available SD4M vari ants cover a<br />
power range between 70 and 490 kW<br />
or 120 and 800 A rated current. The<br />
multiprotocol real-time Ethernet interface,<br />
available on the device as<br />
standard (including PROFINET IO and<br />
EtherCAT), enables hassle-free implementation<br />
of the SD4M in the higherranking<br />
control. An optimal operation<br />
with an external regenerative power<br />
supply is possible using the variants<br />
