DC Current Component Measurement
In the design of high-frequency isolated photovoltaic grid-connected inverter and non-isolated photovoltaic grid-connected inverter, the DC current injected into the grid must be controlled according to different international standards (IEC 62109, IEEE 1547, IEC 61727， UL 1741 ...) (10 mA ... 1 A).
