Description

How it behaves

  •  

What do Lead Frame 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) 1000V / 1050V
Current (RMS/peak) 250A / 300A
Maximum Power * 60kW
Inductance ~ 4mH
Switching Frequency 30kHz - 120kHz

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

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