HIGH POWER DENSITY TRANSFORMERS
Our new ER transformer series is an excellent solution with switching frequencies over 100 Khz and power levels ranging from 2 kW up to 10 kW. With these designs we combine the advantages of helical winding and the use of high frequency litz wire.
The ER-Planars series is suitable for high DC-Link voltage applications. A compact solution for the use as a transformer or storage choke and is particularly good for high power charging platforms in E-Mobility as well for a variety of DC-DC converters in industrial applications.
