with lowEMI levels.With their frequency synchronisation-
capability and very low coupling capacitance, typically
13 pF, EMC compliance is easier.
The converters’ compact design reduces board space
and development time, whilst their characterised dV/dt
immunity of 80 kV/microsecond gives users confidence
in a long service life, and similarly the use of planar
magnetics increases product reliability and repeatability
of performance. Typical applications include motor
drives/motion control, solar inverters, UPS, alternative
energy (wind-power generators), high-power AC-DC
conversion, traction, EV/HEV and welding.
The MGJ6 series converters offer an operating
temperature range of -40 to 105 °C, with derating
above 90 °C. Standard features of the patent protected
converters include enable pin, short-circuit and overload
protection, and a frequency synchronisation pin that
simplifies EMC filter design.
The series is pending IEC 61800-5-1 approval based on
a high working voltage of 690 Vrms maximum between
primary and secondary, and similarly is also pending
UL approval to UL 60950 for reinforced insulation to a
working voltage of 690 Vrms.
As a targeted application solution featuring high
isolation construction, high efficiency electronics and
planar magnetics, no other manufacturer offers this type
of product.
NI Announces Multiple Antenna UE
Support for Its MIMO Application Framework
to Further 5G Research
The provider of platform-based systems that enable
engineers and scientists to solve the world’s greatest
engineering challenges, today announced multiple
antenna User Equipment (UE) support for its LabVIEW
Communications MIMO Application Framework. This
makes the MIMO Application Framework the world’s
only commercially available physical layer reference
design that powers true Massive MIMO prototyping that
goes beyond just desktop simulations to fully functional
5G deployments.
Wireless researchers can pair the MIMO Application
Framework with NI software defined radio hardware to
conduct real-time, over-the-air experiments for a wide
range of MIMO research topics including multi-user
MIMO, single-user MIMO and Massive MIMO. This
multi-FPGA physical layer reference design ships with
well-documented LabVIEW Communications source
code that is fully reconfigurable and modifiable, making
it possible to create a complete network of multiple
antenna devices with minimal system integration or
design effort.
Researchers can now explore beamforming techniques
not just at the base station, but also at the UE to
further improve overall network throughput, extend
cell coverage, reduce interference and more. The
MIMO Application Framework supports a maximum
network throughput of more than 1.5 Gb/s, a flexible
and reconfigurable Time Division Duplex-based frame
structure and a fully bidirectional communications link
that can be used out of the box to conduct Massive
MIMO experiments and seamlessly integrate custom
signal processing algorithms in a fraction of the time
compared to other approaches.
As participants in NI’s RF/Communications Lead User
program, wireless researchers at Lund University in
Sweden have used NI’s flexible prototyping platform
for 5G research and have recently demonstrated the
feasibility of Massive MIMO under mobile conditions for
users moving at both pedestrian and vehicular speeds.
“Massive MIMO has emerged as one of the leading
5G technologies that has the potential to provide
unprecedented levels of spectral efficiency that will be
critical in supporting the vast number of wireless devices
expected to come online in the coming years,” said
Fredrik Tufvesson, IEEE fellow and professor of radio
systems at Lund University. “NI’s MIMO Application
Framework provides the hardware and software
