ENERGY CONVERSION METHOD AND DEVICE Russian patent published in 2002 - IPC

FIELD: energy conversion. SUBSTANCE: energy converter has pair of selector switches each one being installed between positive and negative voltage supplies and common output element connected to load. Modulator functions to open and close selector switches in sequence in which electric currents controlled by them flow in opposite directions in common output element and are summed up at the latter. Modulator has triangular pulse train generator and comparators connected to error signal amplifier to provide for reference switching voltage for comparators. Comparators change over control switches in response to increase in triangle pulse train produced by triangle pulse train generator above or their decrease below reference levels. Converter underlay and overlay are controlled by varying DC current bias level of triangular pulse train. EFFECT: reduced ripples. 13 cl, 13 dwg
