Traction inverters
Microcontrollers
Curtiss-Wright (Christchurch, United Kingdom) expanded
its traction inverter lineup with its second-generation
CWTI. The company claims their latest motor control
software provides increased efficiency between the inverter
and motor. Testing results from electric motors
reportedly demonstrated improvements of up to 38% on
peak torque and power as well as a 2% improvement in
efficiency, resulting in an increased vehicle range of up to
14%. The units are compatible with multiple motor technologies,
including AC induction, permanent-magnet
synchronous and interior permanent-magnet and offer
full fault protection as well as a current and temperature
measured directly on the IGBTs. The temperature measurements
ensure higher power output from the motor,
while current measurements offer superior short-circuit
protection to the system.

Oscilloscopes
RIGOL Technologies
(Portland, Oregon) introduced
their HDO series of
Oscilloscopes. The HDO series
features 12-bit resolution
and are available in 70MHz
- 800MHz bandwidths and 2
or 4 channels. The HDO series also features RIGOL's new
UltraVision III platform with a custom ASIC chipset. This reportedly
provides dramatically lower front-end noise which
will enable users to analyze much smaller signal artifacts
with greater speed and accuracy. HDO4000 oscilloscopes
are available in 200-800MHz with 4 channels and 4GSa/sec
sampling with 100 μV/division range and 250 MPts of memory
standard (500 MPts optional). HDO1000 scopes offer
70-200MHz bandwidth with 2 or 4 channels, 1GSa/sec sampling,
500 μV/division range, and 50 MPts of memory standard
(100 MPts optional). Both series feature 12-bit resolution
and a 10.1-in. intuitive touch screen display.

AUTOMOTIVE ENGINEERING
MikroElektronika (Belgrade, Serbia)
launched a new SiBRAIN add-on
board, the SiBRAIN for
GD32VF103VBT6, which enables
designers to start prototyping with
the GigaDevice RISC-V microcontroller.
SiBRAIN is a standardized
microcontroller add-on board, which allows very simple installation
and replacement of the microcontroller unit (MCU)
on a development board equipped with the SiBRAIN Card
socket. By introducing the new SiBRAIN standard, MIKROE
said it has ensured the absolute compatibility between the
development board and any of the supported MCUs, regardless
of their pin number and compatibility. SiBRAIN is
equipped with two 168-pin mezzanine connectors, allowing it
to support even MCUs with extremely high pin count.

Board connectors
I-PEX (Austin, Texas) released their
new NOVASTACK 35-HDH fully shielded,
board-to-board connector at 1.5mm
(.05-in.) mating height and 0.35mm
(.013-in.) pitch. I-PEX claims this is
the first connector of its size that combines
mating workability with high
electrical performance, while being fully shielded. The connector
features 360-degree metal shielded ZenShield design,
which reportedly reduces EMI emanating from the connector.
This minimizes its impact on the antenna even if the connector
is placed close to the antenna. P-PEX also states that the connector
was designed with signal contacts suitable for highspeed
transmission. The connector is capable of 40 Gbps/lane
transmission and supports the latest transmission standards.

Inverters
Magneti Marelli (Corbetta, Italy)
developed a new platform of
800-volt silicon carbide (SiC)
inverters. The company claims
that its inverter offers improvements
in terms of overall size,
weight and efficiency compared
to competitors. Marelli states that its inverter platform features
an optimized thermal management system with structural and
cooling channel designs that drastically reduce the thermal
resistance between the SiC components and the cooling liquid.
The company also claims that their inverter can extract more
energy from a battery at a higher efficiency and provide a significant
increase in the driving range of an electric vehicle.
