Abstract

The invention discloses a power signal output device. DC power is supplied by a DC power source. A DC voltage regulator is connected with the DC power source and is used for changing the DC voltage input by the DC power source and inputting a DC voltage with a determined voltage value. A voltage power switcher is connected to the DC voltage regulator and can convert the DC power into AC power. TheDC power and / or AC voltage with the determined voltage value can be output through the voltage power switcher. A current power switcher on a current board is connected to the DC power source, and isused for regulating the output current to output the DC power with a determined current value. The power signal output device of the invention can simultaneously output voltage and current with accurate values and loads the voltage and current onto a measured device for detection.

Description

technical field [0001] The present invention relates to the technical field of power distribution devices, and further relates to a power signal output device. Background technique [0002] In the process of testing electrical components, it is necessary to provide voltage and current signals, load the voltage and current determined by the value and phase into the device under test, and calibrate the current and voltage of the device under test; traditional testing devices can only be applied separately Current or voltage, cannot load current and voltage at the same time. [0003] For those skilled in the art, how to design a device capable of simultaneously outputting current signals and voltage signals is a technical problem to be solved at present. Contents of the invention [0004] The present invention provides a power signal output device capable of outputting accurate voltage and current at the same time. The specific scheme is as follows: [0005] A power signal ...
