C Cores Application and Benefits

Applications

For a wide range of high frequencies and hot-spot temperature (up to Class F), C-Cores are used in a growing list of advanced power conditioning applications including:

• Transformers in SMPS (400Hz-20kHz)
• Transformers for inverters in welding equipment, wind turbines and Solar Panels.
• PFC correction chokes in UPS.
• High Power Ballasts.
• Output Filter Chokes in Large SMPS.
• UPS Harmonics Inductors.
• Frequency Converters.
• Automotive Powers.
• Railway Traction System.
• X-Ray Power Supplies.
• Chokes for Induction furnaces.

 

Benefits

• Low eddy current losses
• Low Hysteresis Losses
• High saturation flux density (1.56T)
• Robust design helps in fast assembling into pre-wound coils.
• High efficiency
• Low temperature Rise
• Low Profile - enables weight and volume reductions of up to 50%
• Flexible via individual air gaps
• Up to 70% lower total losses than CRGO
• Allows for operation at higher freq. at same flux level
• Low I²R copper losses
• Less magnetizing current
• Small overall design due to low temp. rise
• Wide operating temp. range = -55°C to +130°C
• Higher power throughput
