VOLTAGE CONVERTER (VERSIONS) Russian patent published in 2012 - IPC H02M3/335 

FIELD: electricity.

SUBSTANCE: voltage converter of the first version comprises an accumulating capacitor, to one of leads of which there is a transistor drain connected, as well as one of leads of an input throttle, and to the other one - a diode anode and one of leads of an output throttle. Other leads of the input throttle and the output throttle form an input and output clamps of the converter accordingly. A filter capacitor is connected to the output clamp by one lead, and its other lead, a diode cathode and transistor source are combined to form a common converter bus. The voltage converter comprises a control circuit, which includes a PWM controller, which is connected by its outputs to drivers, outputs of which form outputs of a control circuit. The voltage converter comprises a switching throttle, the second input and the second output throttles, the second transistor, the second diode and the second accumulating capacitor. According to the second version it additionally comprises a bridge rectifier, current and voltage sensors and a generator of harmonic oscillations.

EFFECT: creation of electric energy converters with provision of soft switchover of transistors with no overshoots of power released on a transistor crystal during transistor start-up and disconnection.
