CONTROL METHOD USING PULSE-WIDTH MODULATION Russian patent published in 2003 - IPC

FIELD: automatic control; electric drives with regulated-voltage power supplies. SUBSTANCE: proposed method intended for power conversion using pulse-width modulation and LC filter in continuous section includes generation of sweep signal from periodic signal proportional to difference between present-time rated increment of output signal and voltage across inductance coil of LC filter for intervals before and after change-over of switching member and increment of bias signal proportional to rated increment of output signal within synchronization period from voltage across inductance coil of LC filter for post-change-over interval of switching member since under steady state conditions supply voltage and output voltage but slightly vary within synchronization period. EFFECT: facilitated control process. 1 cl, 1 dwg
