Power supply regulator 38V
A friend of me one person study about CNC , but stick the problem about power supply of 38V servo motor. Then beg me help to seek power supply regulator 38V Circuit , please. If there is many the circuit or get choose that best. This circuit is one in the choice. It uses Transistor be main part. Follow the circuit Q1 use the number BD139 or the other. For Q2 use 2N3055 highly popular numbers . And Zener Diode use 37V-40V power rate about 1A. The Transformer use 2A sizes. The BD1 use 4A – 6A 200V. Detail other sizes please see in the circuit. I hopes this circuit may in rows think in applying work other , please sir.

Simple Regulator Circuits by JFET
This is uses an N-channel JFET as the pass element to achieve excellent line noise rejection and a bit of short circuit current protection but it is only suitable for light loads. Choose a JFET with sufficiently high Idss to power the load and select R2 as before. The output voltage must be above the pinchoff voltage of the JFET but most JFETs will work if the regulated voltage is above 5 volts.
