Uninterruptible Power Supply (UPS)
Market Demands
  • Zero power downtime (power outages are very costly)
  • Scalable and redundant power systems
  • High power, high current systems
  • Power efficiency
  • Low UPS temperature, minimal use of fans
  • Minimum heat production
  • Power Factor Correction PFC with IGBTs and Fast Recovery Diodes FRD
  • Use of SCRs in the rectifier bridge for inrush-current limitation
