Hi,

In the power electronic circuit, how to synchronize the switching function from TMS320F28335? I want them to start right at the zero crossing of the input voltage!

Hi Ameer,

Can you be a bit more descriptive?

Hi Gautam,
Suppose i generated a switching signals to control the converter switches. I need the sequence of these set of signals be triggered with the zero crossing of the input voltage. Otherwise short circuit will happen!
in other words, if i am using a sinusoidal modulation function to compare it with sawtooth signals and generate the switching sequence! the input voltage to the converter should be in the same phase of the sinusoidal modulation function that i used!
