Figure 1. P04SCT4018KE-EVK-001
This simulation circuit provides the double pulse test simulation environment of P04SCT4018KE-
EVK-001, ROHM’s 4th Generation SiC MOSFET Half Bridge Evaluation Board“. The simulation
circuit is composed of the detailed simulation model with the circuit board parasitic inductance to
achieve higher switching waveform simulation accuracy.
Features
• Double pulse test circuit (High-side switching)
• 4th generation SiC MOSFET SCT4018KE + gate driver IC BM61S41RFV-C.
• Device equivalent circuit model of the components are used for simulation accuracy.
• Parasitic inductors of PCB patterns are modelled and applied to the simulation circuit.
• Vgs, VDC, snubber circuit constants, etc. can be modified.
• Approx. simulation elapsed time is 2min30s.
Applications
• By simulating and verifying the operating conditions and circuit constants of drive circuits, etc., the
workload of hardware evaluation can be reduced.
• By extracting the parasitic L of the pattern from the PCB layout and adding it to the circuit for
simulation, it is possible to improve the problem before prototyping.
• Simulation with the EVK detailed model may help to analyze the cause of noise surge surges
observed in the hardware evaluation.
