Abstract

A sort of pulse-width modulation control apparatus and methods, for voltage-controlled inverters/converters, including a Pesudo Random Binary Sequence (PRBS) generator which outputs a random bit, and a switching state modifier which modifies the switching states of inverter/converter according to the value of the random bit, randomizing the switching state modifier the switching of power devices of inverter/converter, thereby randomizing the spectra of current and voltage, and significantly reducing the acoustic noise and EMI.
