Isolated gate drivers and EMI noise

In power electronics isolated gate drivers are used to drive power semiconductors like IGBTs and power MOSFETS. The gate drivers are used to provide galvanic isolation between the control circuits and the high voltages. They are also used for level shifting to provide high gate voltage and current to switch the IGBT. In industrial applications like inverters and motor drives, EMI noise will be generated by an inductive mode-like motor. The noise may cause reflection, resonance or amplification within the gate drivers and inside the power electronic equipment by its coupling through the wiring.
