An perfectly wired installation will under full load give a ripple of +/- 0,6 to 0,8 volt. much as possible. But the more resistance there is, there more the voltage will drop. • Due to ripple during charging the

The ripple voltage output is very large in this situation; the peak-to-peak ripple voltage is equal to the peak AC voltage minus the forward voltage of the rectifier diodes.

In general, a large dc-link capacitor can significantly reduce the voltage ripple, and smooth dc-link voltage can be obtained. As a consequence, the dc-link capacitors are often oversized. Such
