Vd states the average value (dc component) and declare the filter capacitor voltage ripple. If the active filter is controlled so as to produce the voltage ripple voltage ripple burden no longer contain. In these systems, a passive LC filter is used to reduce ripple and high frequency active filter to reduce low frequency ripple. Therefore, the required size of passive filter is not too large. This active filter can be implemented with a series of linear mode power converters and switching. As mentioned previously, the relationship between the series active filter with a load capacity of the current causes the active filter must be at least equal to the maximum current load, although the low-voltage itself, which is equal to the voltage ripple is compensated. Since a large current capacity required, the application of this method for very large currents will complex and inefficient.
