A rectifier input capacitor's size is often considered nebulous. Therefore, common practice is to pick a large size, and if the ripple voltage is low enough, all is okay (see the figure, a). If not, ...

In the conventional dc-dc converter buck topology (Fig. 1), power from the input voltage source is transferred to the output filter by turning on the pass transistor. When the pass transistor is on, ...

Figure 1 provides a plot of this expression; it is a circle with a maximum of 0.5, at 50% duty factor and two zero crossings at zero and 100% duty factor. The curve is symmetric around 50%. Between 20 ...

Traditional power-supply design practices place much emphasis on the selection and placement of the output capacitor to meet tight ripple and noise requirements. Customers are willing to spend money ...

Although shunt capacitors offer several advantages at all voltage levels, those advantages come at a price. Not only must you purchase, install, and maintain capacitor equipment, you must be able to ...
