Abstract:
Multi-functional and digital control is an important development direction of the power of modern technology. This paper presents a novel high-precision,multi-functionally programmable power supply. The system uses a modular design,including signal generator,a constant current source,multi-programmable regulating circuit,a power amplifier and a touch-screen LCD display module. Design of power provides ±15 V power supply,and to achieve 0-1 200 mA programmable constant current output. It can also be used as high-precision sine wave signal generator output 0-100 kHz,triangle and square waves 0-10 kHz and even arbitrary waveform power supply to achieve more than one machine,reducing the number of laboratory equipment and saving desk space experiments.
