ROHM Solution Simulator Schematic Information
Figure 1. P05SCT4018KR-EVK-001
This double pulse test simulation circuit is based on the circuit configuration of ROHM’s "4th
Generation SiC MOSFET Half Bridge Evaluation Board" P05SCT4018KR-EVK-001 and reflects the
parasitic components of the PCB wiring pattern based on electromagnetic field analysis. By
modeling the EVK implementation and reflecting it in the simulation, it is now possible to accurately
simulate the switching waveforms of the actual device.
Features
• Double pulse test circuit (High-s
ide switching)
• 4th generation SiC MOSFET SCT4018KR + 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.
A
pplications
• 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
obs
erved in the hardware evaluation.
