Power sources
Because of their technology, switched power sources are
highly efficient, more compact and even cheaper than linear
power sources. Therefore they are quite often being used in
compliance test systems for harmonics and flicker. They can
supply the maximum current even under reactive loads with
low or even very low power factors and are superior in this
aspect to linear power sources.
ZES ZIMMER, however, offers linear power sources as well, if
– due to the type of the device under test, respectively the
test to be performed – the output signal ought to fulfill the
following requirements:
•
Minimal distortion of the output voltage
•
Very high frequency band-width
•
Very low output impedance
•
Very high current range without distortion of the output
voltage
•
Exclusion of any possible interaction (resonances or
oscillations) between the (low pass) output filter of the
switched power source and the device under test.

Simplified diagram of switched and linear AC power sources. The
unregulated and distorted AC voltages of the single- or three-
phase input are being converted to regulated and undistorted AC
through PWM resp. linear amplifiers.
