I have a problem while debugging TLE9879QXA40.
What we use the PWM schemes used for BLDC drive system is Low Side Modulation with Synchronous Rectification. But from the display of Oscilloscope we found that the waveform of the voltage of the phase
high is diefferent with the phase low. It has the oblique waves in high phase waveform. Why is his waveform like this? The waveform of phase low is same as theory. Thank you.
