Power Supply +50V 3A stabilized and regulated By 2N3055

Advertisements

Many times we needed a stabilized, together regulated power supply and high relatively output voltage. These specifications him it cover our circuit. It ’s a circuit that can give in his exit + 40V until + 60V 3A, with simultaneous stabilization. The materials that use is very simple and will not exist difficulties in the manufacture, is enough you are careful certain points. 1 ] For output voltages smaller of + 50V until + 40V, the Q1 is hot enough, so that it needs one big heatsink. 2]For output voltages bigger of + 50V up to + 70V, the stabilization is not satisfactory.
