FIELD: electricity.
SUBSTANCE: invention relates to converting equipment and can be used for development of power supplies for various equipment. The voltage converter powered from DC power supply is offered which contains current and voltage sensors, a contactor, a power transistor connected in series with the contactor contact and resistor shunted, step-up regulator based on two power keys and two diodes, DC/DC converter based on a halfbridge and two series connected capacitors, a power transformer, an output capacitance and resistance loaded rectifier, and a control unit.
EFFECT: technical result consists in failure protection of power keys at increase of voltage and current through them that is implemented by means of a certain sequence of switchings of power keys and the contactor from the control unit.
