6 FAQs about [Conductive Voltage Inverter]

Can cm EMI be suppressed in inverter fed motor drives?

This paper reviews suppression methods for the conductive common-mode (CM) EMI in inverter-fed motor drives. It considers both mitigation from the sources and suppression along the conduction paths to span EMI suppression across the full system design process.

How are inverters connected to a load?

In either case, one inverter (inverter “A”) is directly connected to the load (with an output in series or parallel with the load), while the other inverter (inverter “B”) is coupled to the load via an immittance converter (with one port of the immittance converter in parallel or series with the load).

What are the main sources of EMI in inverter-fed motor drives?

The EMI sources in inverter fed motor drives predominantly comprise two elements, viz. the CMV caused by the discrete voltages generated by the inverter and the PWM; the high dV / dt and di / dt generated during the switching transient of power devices. The main conduction paths of common-mode EMI in motor drives
