FIELD: transformer engineering.
SUBSTANCE: transformer includes classic transformer, two back-to-back diode arms, every of which is formed by two sequence diodes, two capacitors, ballast resistor and active load. Common point of diode arms is connected to one of outputs of secondary winding of transformer. Opposite outputs of diode arms are interlocked through ballast resistor. Middle points of diode arms are interlocked through two identical capacitors. Common point of capacitors is connected to active load, second output of which is connected to other output of second winding of transformer.
EFFECT: minimum power loss of transformer and constant transformation coefficient in the range of rated capacity.
