What's Ripple Current in Power Supplies

The post explains regarding what's ripple current in power supply circuits, what causes it and how it can be reduced or eliminated using smoothing capacitor. What's Ripple in Power Supply CircuitsIn all AC to DC power supplies the DC output is acquired by rectifying the AC input power and filtering through a smoothing capacitor. Although the process cleans the AC to almost a pure DC, a small content of unwanted residual alternating current is always left over within the DC content, and this unwa.......
