METHOD FOR CONTROLLING PULSE-WIDTH MODULATED CONVERTER Russian patent published in 2004 - IPC

FIELD: automatic control of bridge converters and the like. SUBSTANCE: for controlling pulse-width modulated bridge converter incorporating LC filter in continuous part with preset waveform of output parameter (current or voltage) control signal is separately shaped for positive and negative polarity of output signal. Two sweep signals are consequently shaped as differentiated output signals of respective polarity predicted for interval after changing over switching components. EFFECT: enlarged functional capabilities of converter due to its high stability and improved waveform of output parameter. 1 cl, 1 dwg
