ALPITRONIC gmbh
Innovation for the future
alpitronic stands for a highly qualified
team of young engineers, specialized in
the development of complex electronic
systems in hardware and software.
alpitronic’s focus is centered upon power
electronics and safety-critical systems.
alpitronic’s commitment and flexibility in
the development of innovative systems
guarantee high quality solutions and short
development times, which are achieved
through a consistent, process-oriented
approach. Model and simulation based
development methods are fundamental
to alpitronic’s ability of innovation.
Common Goals
alpitronic is eager to face the complex
challenge of developing innovative
concepts together with their customers,
from the first idea to the timely
implementation – with competence and
consistency.
alpitronic’s design experts offer support
for conceptual design and dimensioning
of complex power electronic systems,
design of microprocessor architectures
of safety-related applications (ASIL / IEC
61508), circuit simulation, power loss and
tolerance calculations, thermal and cool-
ing system design, as well as optimization
of costs and power losses on existing
circuits.
In the field of system engineering, espe-
cially for automotive power electronics,
alpitronic develops and tests inverters for
traction and range extender applications,
including special solutions like high switch-
ing frequency inverters with alpitronic‘s
ARCP technology. alpitronic’s motor test
bench provides the facilities to do inverter
and e-machine testing, including high
precision power loss determination of
components and the whole system.
alpitronic provides also development and
manufacturing support: schematic and
layout design, production and commis-
sioning of prototypes, handling of the
certification process, handling of small
series production.
Pioneering Technology
alpitronic‘s new resonant switching ARCP
technology for half-bridges allows high
frequency switching of 50kHz and more
at currents of several hundred amperes.
The technology was first realized in a
100 kW inverter prototype (400V DC link
voltage and phase current 250Aeff).
A 550Aeff device is currently in develop-
ment. Switching frequencies of 50 kHz
and more enable new applications like
high-revving, or high pole count, compact
motors. The technology provides weight
and volume reduction of currently avail-
able inverters by 30% through reduced
cooling demand and small EMC filter.
