Switchmode Power Supply
Switchmode Technology
Switchmode power supply units are particularly suited for fee-
ding portable devices. Their low weight and extremely compact
form mean they can be just as advantageously combined with all
other types of applications.
An additional increase in attractiveness results from the wide-
range input so that the power supply units can be operated all
over the world using mains voltages from 100 to 240 V AC and
50 to 60 Hz. This makes worldwide use possible and means a
drastic reduction in the logistics expenses on the part of our
customers.
Such solutions can either be realised as desktop units with world-
wide standardised IEC sockets (our DT series) or as plug-in power
supply units with exchangeable mains plug adapters (our MPP
series). Details regarding these products can be found on the
following pages.
First, here is some important technical information:
Primary Switched Power Supply Units
In such a power supply unit, the mains voltage is first rectified
and smoothed. After that, it is switched at high frequencies and
transferred via a converter transformer. The required low voltage
is then generated within another rectification and smoothing
step. A high-precision direct voltage with very low tolerances can
be provided by means of an additional stabilisation circuit.
Beyond these advantages of the compact design and wide-range
input, the high efficiency is of decisive importance: at an achiev-
able 90 percent, the losses due to emission of heat are mini-
mized. The requirements for very low stand-by power consumption
(stand-by power) can only be met using this technology.
FRIWO offers an extensive range of standard devices with excel-
lent features. At a corresponding volume, further variants for all
kinds of special requirements can be developed. In the process,
the application considerably determines the design:

Safety Regulations, Protection Classes, and Connection
Types
Power supply units can be found in a number of applications. For
this reason, the specific safety regulations of the devices being
powered, depending on the regulation of the testing authori-
ties of the respective countries, such as the UL (Underwriter Labo-
ratories), VDE (Association of German Electrical Engineers), etc.,
must be particularly observed.
The EMC conformity according to EN 61000-6-X, under conside-
ration of system perturbations according to EN 61000-3-2 should
be observed for power supply units independent of the switching
concept.
When selecting the housing, the ambient conditions, for ex-
ample in moist environments, must be considered. For general
applications, the type of protection according to EN 60529-IP20
(Operation in Dry Rooms – Protection Against the Penetration
of Solid Foreign Body) suffices. According to application, power
supply units are designed in accordance with the respective appli-
cable regulations. Due to the safe galvanic separation, all devices
fulfil the low-voltage guideline and provide a safety extra-low
voltage (SELV).
In addition to output current and voltage, requirements
regarding control stabilisation and ripple of the output
voltage, EMC behaviour, efficiency, etc. influence the power
supply unit design.
Specific requirements regarding size and shape have an
effect on the component expense and thus the costs of
the unit.
Various circuit topologies can be used according to the
requirements.
Designs as plug-in power supply units, desktop devices, or
even as modules (= open frame) for all special applications
can also be realised.
