The above is the Voltage profile for Vba and V ca here i am not able to understand the gape between the PWM signals why each of the signals are not continuous.as SPWM is embedded inside them to control the voltage as (zoomed version of Crowded portion from above figure).
From the figure 1-
Frequency as it seems = 1Hz-
But same
Frequency from Figure 2
= 43kHz.
What is the meaning of 1Hz and 43kHz ?
How the above waveform is able to run the motor at different speeds ?
How such SPWM Works i know only one kind of SPWM from literature as -
And it is continuous and have no gaps as seen in the Actual waveform ,Please Help ???
