摘要

Alternating current/direct current conversion circuit, with voltage reduction by means of rectifying chains of capacitors in series. The basic element is a chain of identical capacitors A alternating with diodes in series C, which only charge during the half-cycles of alternating current with suitable polarity, and at an approximate voltage of the peak value divided by the number of them. During the half-cycles of opposite polarity the capacitors discharge in parallel through the diodes B, delivering reduced voltage. The system includes two chains of opposite polarities, so that there is always one charging and the other supplying an output current. An electronic switching system synchronized with the alternating current, is responsible for tapping the output voltage from one or the other chain during the periods of discharge. A claim is made for the circuits for power supplies based on this scheme. Its application lies in the electronics industry. <IMAGE> <IMAGE>
