Characteristics
Hybrid magnetic material reactor enables different magnetic materials to be combined!
- Dispersed gap design
- Using dispersed gaps reduces the magnetic flux concentration.
- Bank coil (patented manufacturing method)
-
- High withstand-voltage structure with minimal electric potential difference between windings
⇒ Improves reliability and safety - Greatly reduced stray capacitance (Cs)
⇒ Less than 1/10 of previous model - Higher resonance frequency range and stable inductance over a wide range
⇒ Ideal for high-frequency drive of power supply switching
- High withstand-voltage structure with minimal electric potential difference between windings
- Hybrid cores (patented manufacturing method)
-
- Enables the design of cores optimized for the unit, such as using an amorphous thin film in C cores, and grain oriented electrical steel in I cores.
⇒ Can meet a wide range of needs by combining different magnetic materials
⇒ Optimized designs contribute to low noise and high efficiency
⇒ Enables compact, lightweight, low-loss designs - Usable with low-loss materials suitable for high frequency drive
⇒ Compatible with future higher unit frequencie
- Enables the design of cores optimized for the unit, such as using an amorphous thin film in C cores, and grain oriented electrical steel in I cores.
- New evaluation device
-
- Enables easy customer evaluation of mounting characteristics (loss and noise)
⇒ Shortens product evaluation process
- Enables easy customer evaluation of mounting characteristics (loss and noise)
