you can see the drop down in the pulses it should be square waveWhat do you mean "shifted", in time, offset ....? I cannot tell where ground is from your
scope shot.

It shouldn't. In discontinuous conduction mode, the switching node shows three levels, also the gate node does. The"drop" indicates D2 conduction phase.you can see the drop down in the pulses it should be square wave
The waveforms are probably different because the load current is different. Looks like now the converter is operating in continuous conduction mode, whereas before it was in discontinuous mode.I changed the dc motor load to resistive load and pulses were pretty good,how to fix the dc motor load problem?
