First question asked Welcome!

When 2ED2181S06F is used to drive the high and low side MOSFET, the low side can be turned on and off normally, but the high side cannot be turned on. The test is conducted under the condition of Vdc=0V when the DC bus is not turned on. The test results are as follows: power supply Vcc=12v, Vb=11.55V, Vho=8.29V, Vs=8.6V. Please attach the schematic diagram and ask for help on the cause and how to solve this problem.

Can you attach your PWM signals (input logics and output gates)?

I think if you take the oscill from logic, gates, and VB you will answer your question on your own:)
