Resonance Transfomer 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).
Resonance Transfomer
Resonant transformer / choke combination
Technical data
Inductance: 72 µH
I = 36 Arms
Input voltage: 370 V, output voltage: 110 V
Is = 80 A; 63 App
Frequency: 20-25 kHz
Pout =15 kW; U = 5.83:1 (350 /60 V)
Description
The two-winding transformer operates on the primary side on a series resonant circuit with a frequency of above 30 kHz (up to a maximum of approx. 60 kHz). This results in a rectangular bipolar voltage shape with 350 V peak voltage and an almost sinusoidal current shape with 50 A effective at the operating point on the primary side (secondary scaled accordingly with transformation ratio).
The power to be transmitted is 15 kW with a transformation ratio of 5.83:1 (350 V primary to 60 V secondary).
The booster choke operates in a step-up converter.
