Aan Posted March 11, 2007 Report Share Posted March 11, 2007 Which one should i connect C to A or C to B ? and why ? Quote Link to comment Share on other sites More sharing options...
audioguru Posted March 11, 2007 Report Share Posted March 11, 2007 Why are there two extra diodes connected to the AC? You don't want to connect AC to ground or to the output of the regulator.Look on the datasheet for a 78xx regulator. It shows the two capacitors that are missing on your sketch.Whay aren't your lines straight?? Quote Link to comment Share on other sites More sharing options...

audioguru Posted March 12, 2007 Report Share Posted March 12, 2007 I think this circuit will detect each zero crossing of the mains: Quote Link to comment Share on other sites More sharing options...
