The invention discloses a multifunctional low-
noise nuclear instrument power supply experimental platform. The multifunctional low-
noise nuclear instrument power supply experimental platform comprisesa supply circuit, an analog-
digital converter ADC, a
digital analog converter DAC, a micro-processor MCU, a capacitive touch screen, a
keying circuit, a storage, an
isolation transformer and a
buzzer. The supply circuit comprises a
rectifier filter circuit, a first low pressure supply circuit and a third low pressure supply circuit, a positive
high pressure output circuit, a negative
high pressure output circuit and a second low pressure supply circuit, wherein the first low pressure supply circuit and the third low pressure supply circuit are both connected with the
rectifier filter circuit,the positive
high pressure output circuit and the negative high pressure output circuit are both connected with the third low pressure supply circuit, and the second low pressure supply circuit is connected with the first low pressure supply circuit; the output of the first low pressure supply circuit, third low pressure supply circuit, positive high pressure output circuit and negative high pressure output circuit is all connected with the analog-
digital converter ADC and the
digital analog converter DAC; and the input of the
isolation transformer is connected with a mains supply and the output of the
isolation transformer is connected with the
rectifier filter circuit. The multifunctional low-
noise nuclear instrument power supply experimental platform has the advantages that the structure is simple, the noise is low, the anti-interference ability is strong, the
voltage output is stable, and the development cost is reduced.
