Resonant Transformer Resonant Transformer

Resonant Transformer 20KW

Technical Data Rated primary inductance: 300 µH Minimum
transformation ratio of 3,3:1:1
Input voltage 370 V
Rated input current: 75 A rms
Output voltage:: 110 V
Frequency: 50 kHz

Description The primary side of the transformer works on a series resonant circuit with a frequency of more than 40 kHz (up to a maximum of approx. 60 kHz). In the operating point, this gives a rectangular bipolar voltage waveform with 500 V peak voltage and an almost sinusoidal current form with 75 A rms on the primary side (secondary side scaled in accordance with the transformation ratio).

The power to be transmitted is 20 kW for a transformation ratio of 3,3:1:1 (370 V primary to 110 V secondary).
