Mitsubishi Electric: SiC-MOSFET/Circuit Simulation: New SPICE model developed
Mitsubishi Electric:
On July 9, we developed a unique SPICE (Simulation Program with Integrated Circuit Emphasis) model.
Highly accurate simulation of switching speed of SiC power semiconductor “SiC-MOSFET”.
What is “MOSFET”:
Abbreviation for “Metal-Oxide-Semiconductor Field-Effect Transistor”.
Transistors use the movement of free electrons and holes in the semiconductor to perform electrical amplification.
Efficient circuit design work:
A simulation that is almost equivalent to the measured value is possible.
Streamlined circuit design work for power electronic devices equipped with SiC-MOSFETs.
Traditional SPICE model:
When simulating a SiC-MOSFET with the conventional SPICE model, there was the problem that “current waveforms generated during high-speed switching operation cannot be analyzed with sufficient accuracy.”
Solved with the new SPICE circuit analysis tool:
When designing electronic devices equipped with discrete power semiconductors,
Element operation of the power conversion circuit,
Device operation in the gate drive circuit
It can be predicted in advance by simulation.
Solve it by simulating with the new SPICE circuit analysis tool.

Mitsubishi Electric Develops Accurate Circuit Simulation Technology for SiC-MOSFETs
TOKYO, July 9, 2020 –
Mitsubishi Electric Corporation (TOKYO: 6503)
announced today that it has developed a highly accurate Simulation Program with Integrated Circuit Emphasis (SPICE) model to analyze the electronic circuitry of discrete power semiconductors.
The technology
is deployed in the company’s “N-series 1200V” SiC-MOSFET* samples of which will begin shipping in July.
The model simulates high-speed-switching waveforms almost as well as actual measurements, on a level of accuracy
currently believed to be unmatched in the industry, which is expected to lead to more efficient circuit designs for power converters.
Going forward, Mitsubishi Electric
expects to add several temperature-dependent parameters to enable its SPICE model to work at high temperature.
The company presented the new model** on July 8 at the International Conference on Power Conversion and Intelligent Motion (PCIM Europe 2020), which was held online on July 7 and 8.
Key Features
Unique SPICE model enables efficien circuit design for power converters
The new model
enables high-precision simulation of the drain current flowing through the power conversion circuit over the entire rated current range.
Circuit designers
can spend less time complementing data with experiments, raising work efficiency from the early stages of power converter development.
