The demands on the power supplies are two-fold - maximum efficiency and
minimum noise. Maximum efficiency reduces power dissipation in the unit.
Temperature impacts reliability and stability. To achieve maximum efficiency, the
primary converter is a switching converter with an efficiency of approximately
90%.
High efficiency of switching converters is well known and holds a major position
in the power supply industry. But one of the problems with a switching converter
is noise. By its nature, a switching power supply must use fast rise and fall times
of the switching elements. These fast edges generate high frequency noise. The
power supply chosen has a noise level that is more than 50dB below primary. To
further reduce noise, the power supply is in its own enclosure and is followed by
a noise filter. The filtered power is then used by width bandwidth linear regulators
to further reduce noise.
