ABSTRACT:
In a method of generating pulse-width modulated waveform, the cycle of a carrier wave for the waveform is determined together with a first dead time value and a second dead time value both of which are set in a plurality of up-down counters, respectively. Using the plurality of the up-down counters is effective to assign individual dead times to upper and lower arms and to linearly control a PWM duty from 0% to 100%.
