2.3.1 Ripple regulation
2.3.2 Definition
2.3.3 Ripple voltage test circuit
2.3 Output Ripple
The ripple voltage of the outputs shall be measured at the pins of the output connector when
terminated in the load impedance specified in figure 1. Ripple and noise are measured at the
connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic capacitor to simulate system
loading. Ripple shall be measured under any condition of line voltage, output load, line frequency,
operation temperature.
