In many industries an increasing need at modern power supply
systems exists. In the processing industry e.g. generators
are used increasingly for technological processes such as
electroplating, plasma technology, induction heating or
for test stands. In those fields high power levels up to
10-100kW are needed. Converters of high power are also used
in the railway technology.
Further areas of application are battery chargers for electric
vehicles, load electric rectifiers for telecommunication
stations, power supplies for the house and illuminating
engineering. During the use of regenerative energies (photovoltaics,
fuel cell, wind generator) adapting converters between the
energy source and the mains and/or consumer loads are needed.
All these applications cover a large power range.
The moreover mass-markets for power supplies of smaller
power levels exist (< 500W). Here the production costs
are the center of attention. SMPS for PC, server, communication
and entertainment electronics are manufactured in enormous
numbers of items. The market for lamp ballasts for halogeneous
and fluorescent lamps is also increasing. In the automotive
engineering by the increasing number of electrical consumers
and decentralization of the utility systems increasingly
power supply modules are needed.These must be characterised
by highest reliability.
Our activities cover the development of complete power
supplies in accordance with product requirement specifications
up to the support of the introduction to the production
process with the client or the own manufacturing of a small
series. Substantial work procedures are:
-
development of the circuit concept
-
selection of the power semiconductors
-
dimensioning of the passive components
-
dimensioning of the cooling system
-
development of the control concept, selection/ design
of the control hardware
-
Software-Entwicklung
-
software development
-
PCB development
-
preparation of certification/ EMI suppression
-
preparation of production documents/ documentation
Developments up to the phase of the operating model or
prototype are also possible. The moreover we offer concept
studies or the design of individual converter components.
This concerns in particular the computation and optimization
of magnetics.
Further fields of activity are measuring services, e.g.
the measurement of the line-bound radio interferences and
line harmonics (conformity EN61000-3-2). Likewise we offer
problem solution at existing systems and their revision
or modification.
