As the flowchart shows, if m* is <0.866, duty cycles are calculated as the linear mode operation; otherwise, if m* is <1.15, mode I is selected, and if m* is >1.15, first 0.284 (1.15 − 0.866 = 0.284) is subtracted from m* , then, …
Web17 May 2016 · That's the algorithm I'm using, indeed. And the SPWM signal is absolute identical for every pair of positive and negative half waves (as the PWM attenuation is changed at the begining of positive half wave only). But what could be the influence of load changing (especially of an inductive one)? WebSPWM has three modes of operation: mode 0, mode 1, and mode 2. Mode 0 is indicated by host sequence bits 00. A repetitive waveform is generated in which the rising ...
