AI Technical Summary
Existing photovoltaic inverter temperature rise and electromagnetic interference testing systems cannot achieve synchronous acquisition and real-time linkage of temperature data and EMI signals, and cannot reveal the dynamic coupling process between the two, resulting in low efficiency of coupling analysis of photovoltaic inverters.
Design an inverter temperature rise and electromagnetic interference synchronous acquisition and coupling analysis system, including a temperature rise acquisition module, an EMI acquisition module, a synchronous control module, a power acquisition module, a coupling analysis module, and a data storage and display module. Through fiber optic temperature sensors, thermocouple sensors, infrared thermal imagers, conducted EMI and radiated EMI acquisition units, FPGA clock source and trigger logic, power loss calculation, and multi-dimensional data synchronous acquisition and analysis, a power-temperature rise-EMI coupling mapping model is constructed.
It enables simultaneous acquisition and analysis of temperature rise and EMI data, clearly presents the coupling relationship, improves the operational stability and reliability of photovoltaic inverters, extends the service life of devices, and solves the problem that existing tests cannot reveal the coupling degradation mechanism.
