Description
technical field [0001] The invention relates to a voltage source device, in particular to a digital control multi-channel voltage source device. Background technique [0002] With the advent of the information age, the demand for digitally controlled voltage sources is increasing because of its advantages such as easy control box and system interface, but so far, the method of realizing digitally controlled voltage sources is generally to use A conversion, that is, first convert the digital signal of the control voltage output into an analog signal, and then process it to obtain the required output voltage. At the same time, the power supply of the voltage source generally does not have a protection function, and is lacking in safety performance. Contents of the invention [0003] The object of the present invention is to provide a digitally controlled multi-channel voltage source device, which can completely solve the above problems. [0004] In order to achieve the ab...
