Abstract: A transformerless direct current power supply having a regulated voltage output is disclosed. The supply uses cascaded sections of capacitive series voltage dividers in series to reduce and store full-wave recitifed DC input voltage which is then discharged in parallel at the desired output level. The charging and discharging of the cascaded capacitive series is regulated by a switching network driven by a feedback voltage derived from the output to regulate the charging of the capacitors in series and discharge of them in parallel.
