AC to DC power supply ripple

Filed Under (Issues/Fixes) by on 06-10-2014

ASTEC AA16130 power supply provided by Dr. Hintz for our senior design project is being used to power up Dr. Hintz’s alkalinity measurement protoytpe and also our INA116 amplifier. During our lab testing we found out that the (-12 V) outputted by the power supply had a AC ripple as to clean DC signal. In order to get rid of the AC ripple, we installed 2200uF electrolytic capacitor on the (-12 V) of the power supple and got rid of the AC ripple. On the positive 12 volts we saw clean DC signal on the oscilloscope.0
