摘要：NOVELTY - The device has an embedded controller (1), a signal acquisition circuit (2), a driving circuit (3) and a power circuit (4). The current sampling terminal of the signal acquisition circuit is connected to the first signal input terminal of the embedded controller through a first isolation amplifying circuit (5). The embedded controller calculates a pulse width modulation (PWM) signal according to a preset algorithm. The driving circuit drives the power circuit to control the power supply to be tested to output a stable current and a stable voltage. USE - Smart power parameter detection device. ADVANTAGE - The preset power supply technical parameters can be conveniently input through the keyboard input circuit, which greatly improves the practicability of the power parameter detection device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of the smart power parameter detection device. (Drawing includes non-English language text) Embedded controller (1) Signal acquisition circuit (2) Driving circuit (3) Power circuit (4) First isolation amplifying circuit (5)
