Fuji’s New IGBT (Insulated Gate Bipolar Transistor) and related inverter can achieve High-Efficiency Power supply as follows

  • Around 3% energy saving
  • 50% of space saving for power unit part
  • Maintain power factor 0.98 or more → Save transformer capacity by 20%
  • Reduce harmonics by multi-pulsed rectifiers → Cancel harmonic filter
  • Melting speed up (by 6%) → Reduce rated power by 15%
