SINGLE-PHASE ASTABLE CONVERTER Russian patent published in 2014 - IPC H02M3/338 

FIELD: electricity.

SUBSTANCE: proposed device relates to the field of pulse equipment, namely, to DC current or voltage converters. The main area of application of the converter is conversion of rectified grid voltage into lower voltages or DC current, however, devices of the proposed type may be used in any transformer converters and also converters with inductive load. The converter comprises a key transistor (1), the output electrode of which via a transformer is connected to the load, a resistor-sensor of current (2), a circuit of negative feedback (3), a threshold element (4), a voltage feedback circuit (5), a voltage amplifier (6) with a double-phase output, a source of power supply (7). The difference of the proposed device from the prototype is application of the double-phase voltage amplifier (6) connected between the output of the threshold element (4) and the input of the key transistor.

EFFECT: increased efficiency with simultaneous expansion of functional capabilities.
