Description

How it behaves

  •  

What do Edge Wound Planar Transformers aim to solve

  •  

  • AC circuit filter → attenuate high frequency noise, in series with current pathway, from harmonics in AC current → “AC choke” or “ AC power choke”
  • Maintain inductance over specified frequency range

+ Low parasitic capacitance → High self-resonant frequency > 5MHz *

* High inductance or inductors with many turns → lower self-resonant frequency

Voltage (RMS/peak) 48V / 60V
Current (RMS/peak) 350A / 400A
Maximum Power * 45kW
Inductance ~ 50µH
Switching Frequency 100kHz - 300kHz
Efficiency > 98%

* Switching above 300kHz limits max. power, whereas lower frequency will extend the given power range

  • Passive filters
  • Resonant and phase-shift converters/inverter topologies
