Problems solved by technology

Since the load signal does not refer to the voltage of the object under test, it is impossible to respond in real time to the change of the output voltage of the object under test, so it is impossible to truly simulate the actual load characteristics. The present invention is to improve this problem.

Embodiment Construction

[0033] The present invention mainly uses digital control technology with active electronic load modules, voltage and current measurement circuits and high-speed digital hardware equipment, such as: digital signal processor (DSP), analog-digital converter (ADC), digital Analog converters (DAC), etc. to simulate rectifying passive load circuits. Users can input series resistance Rs, series inductance Ls, load capacitance C and load resistance R according to their needs L Refer to the current voltage of the object under test in real time for the setting value, and then use digital control technology and high-speed digital hardware equipment to process and calculate the load current, and perform a load action on the object under test based on it. In this way, the characteristics of the actual rectifying passive component (RLC) load can be simulated, thereby achieving the purpose of reducing the volume of the load and making the operation more convenient.

Abstract

The invention relates to a rectificative passive type load simulation device and a method thereof, which are used for testing the performance of a power supply product. The simulation device comprisesan analog-to-digital converter, a digital signal processor, a digital-to-analog converter and an active type electronic load module used for replacing a passive assembly in traditional rectificativepassive type load. The simulation method comprises: (S1) a plurality of passive components in rectificative passive type load are replaced by a digital control module and an active type electronic load module; (S2) a passive type load model function is established for representing the actuating relation of the passive components; (S3) the operation of the passive type load model function is performed by the digital control module to obtain a load current value, and the load current value is converted into a simulation control signal by the digital control module; and (S4) the active type electronic load module is controlled by the simulation control signal so as to perform a carrying action to the power supply product.

Description

Technical field [0001] The invention relates to a rectifying passive load simulation device and method, in particular to a device and method for simulating a rectifying passive load using an active electronic load. Background technique [0002] AC Source products, such as UPS and other power supply equipment that can generate alternating current, are widely used in daily life, and their applications cover general information, communications, consumer electronics, transportation equipment, and industry In the field of equipment and military, its function is to drive each circuit unit and maintain the voltage level, which is an important factor for maintaining the normal operation of the system. Therefore, in addition to cost reduction, the main consideration in the design of power supply devices is high reliability. [0003] Generally, the load of AC power products is mostly business equipment, otherwise it is no load. The load characteristics of these transaction devices are rect...
