EMI Noise Testing and Diagnosis for PV Inverter

Article Preview

Abstract:

In this paper, a new method is proposed to test the conducted and radiated electromagnetic interference (EMI) noise of photovoltaic invert based on analysis the internal structure and measuring principle of artificial mains network, meanwhile, the power line radiated EMI noise of photovoltaic can also be estimated by CM noise current using current probe and CM noise extraction network. The experiment result show that the conducted EMI noise and radiated EMI noise of photovoltaic inverter can be test more reasonable by this method.
