Auch Gleichstromspannungen produzieren - dort wo sie verlaufen - Elektromagnetische Felder. Die Auswirkungen des High Frequency Switchings in Invertern sind natürlich gravierender.

"..... The electromagnetic interference (EMI) produced by an inverter can be indirectly related to the input current, but it is not solely dependent on it. Several factors contribute to the EMI generated by an inverter, including:

Switching frequency: Inverters use high-frequency switching to convert DC to AC power. The switching frequency can influence the level of EMI produced, with higher frequencies generally leading to increased EMI.

Input voltage: Higher input voltages can result in higher EMI emissions due to increased electrical stress on the inverter components.

Input current: Although not as significant as switching frequency and input voltage, higher input currents can also contribute to increased EMI generation, particularly in the conducted EMI emissions through the input cables.

Power rating and inverter topology: Different inverter designs and power capacities can have varying EMI characteristics.

Quality of components and EMI mitigation measures: The use of high-quality components and proper EMI mitigation techniques (e.g., filters, shielding) can significantly reduce EMI emissions."
