The electric circuit is a type of constant current paralleling supply, it has the features of high speed, low noise, low internal resistance. Adopting the LM317 as a constant current source, it can provide constant current with 560 mA to load. The field-effect tube 2SR3D and luminotron tube can provide low noisy reference voltage. The LM741(Operational Amplifier) is an error amplifier to compare and amplify the reference voltage and sampling voltage. Two sets of 3DD15 are been used to adjust output voltage to hit the purpose of stabilizing the output voltage.
