| Abstract: | This paper mainly researches a CNC DC power supply controlled by SCM system and output by DAC, which can produce a variety of stepped voltage and current. First a stabilized voltage supply of ±15V is made, supplying power for SCM, DAC and other chips. How D/A conversion chip TLV5618 generates voltage source and how the error amplifier TL082 in current source selects and calculates parameters during the production of NC Power are studied. |
