H bridge operation at a lower voltage level

Hi everyone,

I have designed a H bridge circuit and now it s time to test it.
but the circuit is designed for 300 V DC.

To start with, I thought of starting with a lower voltage level say 48 V DC and then step up slowly to 100.........300 V .
Is this the right way to go?( Because the bootstrap capacitors and many other components are rated for 400 V and I am a bit skeptic.

some kinda tips would be really helpful.

Thank you.

here is the link to my schematic.
