I think the diagram is not clear. Some companies show that picture and the ON-edge or OFF-edge pass through the transformer. Other companies show the same picture, but the transformer is connected to a 200mhz oscillator. This is much the same as a RF carrier with data.And this seems to indicate AC coupling thru signal chain which would mean
not 100 %......

From my experience, the topside drivers that cannot do 100 are limited by the way the top side power supply is created. Here is an example where the top side supply is created by D1 charging C1,2. I have used a different supply that does not use D1 charging, and it does work to 100%.
In our portfolio we don't have any dedicated gate driver for 100% duty cycle/ 0 Hz frequency operation,
You can try this 0Hz operation by adding a charge pump circuit and a timer-based circuit to the gate driver.

Thanks, sorry but are you sure about it, i thought they were capacitively coupled (IR2110), and so woudlnt respond to a constantly high dc input?....ie, it woudl need to constantly change?From my experience, the topside drivers that cannot do 100 are limited by the way the top side power supply is created.

The high side cap coupled circuit, has a Flip Flop. A rising edge sets the FF and a falling edge resets the FF. Once set I see no reason it needs set again to stay on.sorry but are you sure about it
Thanks, infineon forum told me they dont do any 100% duty cycle gate drivers...
