Designed to anticipate future requirements and go beyond current standards, our test facility enables DC/AC and DC/DC converter testing, performance and efficiency analysis, as well as support for the development and optimization of control strategies.

Our Inverter Testing Expertise

Our teams carry out test campaigns tailored to the different development and validation stages of power converters and inverters:

  • DC/AC and DC/DC converters
  • Efficiency analysis (P, U, I)
  • Harmonic distortion measurement
  • Thermal management and mapping optimization, including the impact of the cooling system
  • Lifetime testing: WLTP and mission profiles
  • Electrical fault simulation: short circuit, AC or DC open circuit, overvoltage and undervoltage
  • Validation of hardware (power electronics) and software technology choices
  • Development of electric motor control strategies (speed/torque) and inverter control strategies (PWM)
  • Support for control strategy optimization and development, focusing on performance and safety
  • Benchmarking
  • Run-in testing / COP

These tests enable us to characterize the efficiency and behaviour of power converters under different operating conditions and identify opportunities to optimize their performance.
