Hi,

in ucc28070 controller based ac-dc converter design getting overlapping in boost inductor currents even though the pulse sequence is 180deg phase shift because of that interleaving not working properly.please help me debug this problem.

    Hi Harijarani,

    The gate drives waveforms look correct. It is possible that the boost currents will be overlapping, why do you think that this is a problem. Can you show the boost inductor current waveforms associated with the gate drive waveform plot.

    Thanks

    Peter
