Inverter efficiency
- Materially eliminates switching losses
- Enables higher switching frequencies without increasing semiconductor temperatures
Inverter Efficiency Comparison
- The inverters are operated at 470V, 670V and 870V
- Partial load (5A, 14.7kV/µs) is used for comparison as conventional inverter could not achieve full load at higher voltage levels
- Measurements were made at 10 kHz, 40 kHz, and 60 kHz at each voltage
