Design of power tester for HPLC power line carrier communication module

Abstract

The current equipment used to test the power consumption of power line carrier communication modules not only has low dynamic power consumption, but also fails to meet the accuracy requirements for AC power tests. Based on a careful analysis of the key technologies of the dynamic power test of the communication module, this paper designs a power tester. This paper introduces the working principle of the power tester, discusses the corresponding circuit design scheme from two aspects of DC power consumption and AC power consumption, and analyzes the calculation methods of the two in detail. Finally, the test results of each test system are compared and analyzed. The power tester can achieve higher accuracy data testing.
