Power Electronics Device Modeling
■Power Electronics (PE) design engineers are under strong schedule pressure to address the growing needs of power conversion, motor drivers, etc. Meanwhile, to enable smaller designs, the switching frequencies are going up into the 100s of kHz and even low MHz. While these might be modest frequencies, the voltages, and in particular, the changes in voltages versus time (dV/dt) are very large. GaN devices today are switching within 250 ps, generating harmonic content into the GHz range. Inductances as small as 0.1 nH can reshape the waveforms driving the gate, causing ringing and transient induced noise. Stray inductance in the high current path is very common, leading to large L*di/dt.
■These surges in voltage and current, along with the ringing that follows can cause circuit malfunction, and in some cases, circuit explosion. The high switching frequencies and associated harmonics lead to undesirable electromagnetic interference.
