Output Ripple and Noise
To improve accuracy and repeatability of ripple and
noise measurements, Power-One utilizes the test
setup shown in Figure 12.
Figure 12. Output Ripple and Noise Measurement Test Setup
A BNC connector is used for the measurements to
eliminate noise pickup associated with long ground
leads of conventional scope probes. The connector,
a 0.1 μF ceramic capacitor and a 10 μF tantalum
capacitor, and the load are located 2-3” away from
the converter.
