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.
