Leakage transformer

RUT 500

Unique Selling Point


  • Space-saving (transformer and choke in a single component)

  • Longer life for motors by limiting of current peaks

  • Low-cost

  • Optimized for railway operation (high degree of pollution , Shock- and vibration tested ,
    Salt spray and immersion tested)

Description


In railway applications, where it‘s about the greatest possible comfort and safety of passengers, components are required that save space, are safe and have a long service life. Supply interruptions or voltage drops can lead to a range of undesirable effects such as the loss of motor power. 

The REO leakage transformer ensures harmonized current and voltage outputs, filtering harmonics, and limiting the ripple current.With the spatial separation of the primary and secondary windings and the resulting intentional increase in the magnetic leakage field, the REO leakage transformer achieves a loose magnetic coupling. 

This results in the combination of the function of a transformer (transforming voltage with galvanic separation) and a current-limiting choke.

Leakage transformer

Construction

The primary winding covers both iron cores; the secondary winding only the non-gapped transformer core. The leakage inductance is defined such that in combination with a downstream capacitor, this forms a low-pass filter for attenuating the pulse-frequency current and voltage components.

To illustrate the action of a leakage transformer the input and output currents and voltages for different frequencies were displayed on an oscilloscope. Comparing the different measurements, it can be seen that the currents and voltages at the output of the leakage transformer are more „harmonious“, i.e. from the interaction of the leakage inductance and the capacitor bank, an LC filter results that filters out the higher harmonics and limits the ripple current. 

The higher the switching frequency of the converter, the greater is the effect of the filter.
