TRANSISTOR VOLTAGE CONVERTER Russian patent published in 2012 - IPC H02M1/40 

FIELD: electricity.

SUBSTANCE: transistor voltage converter, comprising a power transformer (PT), a load, a magnetisation current sensor (MCS), the first and second supply inputs, the first and second power switches (PS), emitters of which are connected with the first supply input, there is a threshold device (TD) introduced, a converter output voltage sensor (OVS) magnetically coupled with the PT, the first and second summator, a peak detector (PD), an integrator, besides, the OVS output is coupled with the first inlet of the first summator, the outlet of which is connected via the integrator with the first inlet of the second summator, the outlet of which is coupled via the TD by control inlets of the first and second PS, at the same time the MCS outlet via the PD is coupled with the second inlet of the first summator, and also with the second inlet of the second summator, the first and second inlets of MCS are coupled accordingly with the end of the first and start of the second windings of the PT, the third and fourth inlets of the MCS are connected accordingly with the start of the third PT winding and the load, the fifth and sixth inlets of the MCS are coupled accordingly with the outlet of the first and second PS, the end of the third PT winding is coupled with the load, the start of the first and end of the second PT windings are coupled with the second inlet of supply, the start of the converter OVS winding is connected with the first supply inlet.

EFFECT: higher efficiency of a converter through reduction of magnetisation current.
