Apojee GmbH
Company
APOJEE GmbH is the German subsidiary
of APOJEE SA, the French company cre-
ated in 1999. With its 50 engineers and
technicians, APOJEE develops and sup-
plies high-technology in the fields of
power electronics, test benches and igni-
tion /combustion. Thanks to the skills of
its recognized experts, the company both
develops its own products but also cus-
tomer specific ones. With its experienced
engineers in the spheres of electronic
and mechanical R&D, embedded soft-
ware, multiplex systems, electromagne-
tism and modeling, production engineer-
ing and quality, APOJEE has skills covering
the entire life cycle of a product. The com-
pany works with the major European au-
tomotive, aerospace and industrial players.
Power Electronics Know-how
Expertise in power electronics is one of
APOJEE’s key strengths. Performance, re-
liability and cost also depend on the me-
chanical, thermal management and the
EMC: APOJEE possesses all these skills.
The company defines specific products,
conducts studies and then designs fitted
architectures which leads to the creation
of prototypes or pre-series. It finally
supervises the whole industrialization
process. Some significant products are:
power supply for aerospace – Electronic
hybrid automotive suppliers – inverters,
DC / DC converters for electric/hybrid
vehicles – embedded or external fast
chargers (up to 43 kW). It also develops
and produces a technology-based silicon
carbide inverter. This motorsport inverter
delivers 150 kW for 2.2 l. APOJEE experts
have been using their thorough know-how
in the automotive power electronics to
contribute to the development of hybrid/
electric vehicles for car manufacturers
and suppliers, but also, to the definition
and design of aeronautical power supply.
Today, APOJEE is a team of over 30 people
dedicated to the design and develop-
ment of products incorporating power
electronics.
Test Benches
To cope with the market demand, APOJEE
developed and produced an innovative
and modular testing system for the vali-
dation of power electronics components:
Marvel. Highly standardized and widely
deployable to reduce both investment
and operational costs, Marvel is able to
deal with the new functional require-
ments of future projects. A bay can take
up to 22 modules reaching a maximum
power of 440kW (220kWDC+220kWAC).
Marvel’s inverter has a high switching
frequency (70 kHz) reducing current/
voltage ripple, giving higher dynamic
performance.
Ignition & Combustion Expertise
Complementing its power electronics
and high voltage know-how, APOJEE is
expert in combustion phenomena: the
company contributes to the optimization
and improvement of gasoline internal
combustion engines. APOJEE supports its
customers in their combustion analysis,
designs and develops prototypes or sys-
tems that are specific to ignition (spark
plugs, ignition coils). It also provides in-
novative test equipment intended for en-
gine as well as ignition system designers.
APOJEE works with European OEMs, Tier
1’s and various Formula 1 teams.
