Powertrain, Electric | Power Electronics EMC Crosstalk Prediction and Prevention • High-fidelity PCB stack modeling: − PCB performance analysis, such as DC losses and power/signal integrity (SIWave, Q3D). − Visualization of magnetic field and optimization of traces (HFSS). • Able to pinpoint board region(s) where crosstalk occurred. • Design change suggested, achieved 75% reduction of noise levels and great correlation with measurement. • Avoid program launch delay ($9M/day), established PCB/power pack workflows to avoid future issue between original equipment manufacturer and supplier. • Understand and mitigate signal noise on gate driver printed circuit board (PCBs). • Avoid the fault of simultaneously turning on the high and low side metal-oxide semiconductor filed effect transistors (MOSFETs)/insulated gate bipolar transistors (IGBTs) on the power PCB, causing short-circuit from power to ground. Original design, signal crosstalk observed New design, signal crosstalk avoided ▪ DC losses ▪ Power & Signal Integrity Time Domain Cross-talk Waveform Viewer ▪ High frequency magnetic field ▪ Optimization of traces Engineering Goals Benefits Solution
