Industry challenge

Power is converted at every stage of generation, transmission, distribution and consumption. It matters in both traditional and renewable energy industries. The demand for power is insatiable, the pressure on efficiency, cost and reliability relentless.

Effective switching between medium and high voltages governs the energy efficiency at every stage of generation, supply and usage.

The challenge to improve demands close control of switching characteristics and close monitoring of performance and reliability.

Today's technology

  • On/off switching
  • Costly snubbers
  • Voltage overshoot
  • Over specification of power transistor voltage
  • Inefficient power conversion
  • Repetitive bespoke design every time
  • Limited device visibility

Traditional Switching Waveform

Traditional gate drives require the designer to choose between fast switching with minimal switching losses, overshoot and ringing, or slow switching with high lossess and no overshoot

Amantys approach

  • Controlled switching characteristics
  • Eliminate snubbers
  • Eliminate overshoot
  • Specify the device at the voltage rating you need
  • Reduce switching losses
  • Design reuse, common digital interface
  • Black Box monitoring of switching characteristics

Amantys Switching Waveform

The Amantys gate drive controls both switching rate and overshoot, allowing the best of both worlds: low switching losses, and controlled overshoot.

Amantys allows the best of both worlds:
