Abstract
Disclosed are apparatus and methodology for providing a capacitive voltage divider configured to reduce a relatively high level alternating current (AC) to a lower level direct current (DC). The apparatus provides a series of capacitors and diodes configured for series charging of the capacitors and parallel discharge thereof by way of a single switching element. In operation, the capacitor series is charged during the negative half cycle of the AC source and then discharged during the positive half cycle thereof.
