DIRECT CURRENT CONVERTER Russian patent published in 2013 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: device contains an inductive pulse commutator, the secondary winding of the transformer, the rectifier key, filter capacitor, comparator, driver, an auxiliary diode, the transmission circuit of capacitor- or transformer-type of ripple voltage variable component and also constant component regenerator containing a capacitor and switching transistor; there is also an auxiliary diode connected in parallel to the rectifier key in direction corresponding to direction of the rectified current passage, the transmission circuit of ripple voltage variable component connected between the filter capacitor and one of the comparator inputs while its second input is connected to the common bus; at that the filter capacitor is made in the form of serial connection of the capacitor and low-value resistor.

EFFECT: increasing efficiency coefficient of DC converter rectifying section with simplification of its structure, especially for a transformer embodiment.
