ABSTRACT:
Current-return diodes around input capacitors permits the use of polarized isolation capacitors in a.c.-to-d.c. power supplies. By providing input diodes, the use of more efficient polarized (d.c.) capacitors can be used as the a.c. isolation element, providing surge limiting protection and larger currents at reduced costs.
