Thanks~ I did a circuit, but found ineffective regulator, for example, in the 3A maximum current range, adjust the voltage of 20V, but the addition immediately after the load into 16V. What is the reason?
I did not express clearly I have a two-winding transformer secondary, double winding with center tap voltage 2X25V, I can use full-wave rectifier rectifier? Means that this part of the rectification circuit using only two rectifier diodes, rather than the full-bridge rectifier In addition, the circuit is able to use CA3140 LM741 operational amplifier?
Hello, audioguru , I have one question I have a two-winding transformer, rectifier whether the Department can use full-wave rectifier? My English is poor, thanks for your answer ~
