  • Reproduces the combination of stresses in harsh environments

  • Enables product design that accommodates various operating environments

  • Improves the insulation reliability of power electronics equipment

As the application of power electronics equipment is expanding, there has been increased usage in harsh environments, such as at sea and at high altitudes.

However, conventional insulation evaluation technologies cannot fully reproduce the conditions of harsh and complex environments. Therefore, we have developed an insulation reliability evaluation technology that simulates combined stresses by adding environmental loads (atmospheric pressure and contamination) to conventional electrical and mechanical loads. This technology is contributing to improving product reliability.
