FIELD: electricity.
SUBSTANCE: proposed energy conversion device is made from an attachment, made in form of an assembly of apparatus (8, 15, 22) aiding communication, in series, between an alternating current lead-out terminal (7, 14, 21), fitted in a current-type energy conversion device and an alternating current load (29). The communication aiding apparatus has a reciprocal interlocking type internal commutation device (9, 10, 16, 17, 23, 24) and capacitor (11, 18, 25). By controlling switching of the reciprocal interlocking type internal commutation device (9, 10, 16, 17, 23, 24), voltage is generated at the capacitor (11, 18, 25), and that voltage is further used in switching power supply.
EFFECT: design of a device which can be easily and cheaply made, and which provides for high power and has an improved power factor.
