Key Features

Mechanical Simulation

  • Standardised power semiconductor solution for soft-start application
  • Serialised parts with more than 10 power ratings to meet various application requirements
  • Standardised design dedicated to reducing the complexity and workload of soft-starter design
  • Compass structure, power stack and bypass, enables the switch to be integrated into typical soft-starter cabinet
  • Easy to mount and maintain without auxiliary thermal grease

Mechanical Simulation

  • Centre distributed gate control
  • Sealed housing structure with inert gas protection enable improved PC capability and reliability
  • Thermal design to inforce thermal resistance performance
  • Automatic production platform, suitable for mass production

Mechanical Simulation


ANSYS Software Mechanical Simulation

Optimised heat sink structure and module design to enhance thermal performance and soft-start.

Stress simulation is adopted to optimise the module assembling structure and integral design.
