Sources and effects of powertrain drive common mode noise
A typical block diagram of a hybrid powertrain drive is shown below. When the gate drivers switch the high side and low side IGBTs (insulated gate bipolar transistors) in sequence, high dV/dt noise is generated. For example, a typical powertrain connected to a high voltage 400 VDC with the switching rise and fall time of 50 ns, will generate dV/dt noise of 400V/50 ns ~ 8 kV/μs whenever the gate driver switches.
