What do you mean by "complementary PWM"? Where do you change the PWM fill rate?

I don't Cube.

Better have a drawing of the waveform and some timing information.

Very fast PWM frequencies can be achieved using timer in toggle mode updated by DMA writing from circular compare table, similar to a burst pulse generation with control of each edge.
