Hi guys,
I am new in here, I do master about motor driving .I designed a basic full h bridge card,But I has a problem that is only pozitve wave.My stm32 card give 2 pozitiv signal inputs of ır2101 .Ir2101 drives pozitive wave,not ac wave.I sent us my document

 

You show two different circuits, one with a not gate and one without, which is correct and where are your scope probes attached too ?

fass.png is spwm signal usage, mm.png is for ac pwm .
I want to do ac wave on load. I applied 2 positive wave hin and lin , and I want to current flows forc + and - ways
