The basic principle of the linear dc power supply:
High power dc voltage constant-current power supply from the transformer/step-down benchmark, rectifier, filter, power supply circuit, voltage reference circuit, voltage regulator, steady flow amplifying circuit, adjusting circuit and steady flow sampling circuit, etc.
When the output voltage changes due to the power supply voltage or load current changes, the changes of signal is compared with the reference voltage by the voltage sampling circuit, the error signal obtained after comparing amplifier amplification, linear adjustment device for fine adjustment, make the output of high-precision dc voltage source
