Hello PengYinkui,

So the HO1 voltage waveform is unexpected? how do you measure this waveform? is it between HO1 and VS1 or HO1 and COM?
If it is between HO1 and COM, please also measure the voltage between VS1 and COM.

If it is between HO1 and VS1, then please measure the waveform between VB1 and VS1 together in the same pic.


Best Regards,
Daisy

Hello Daisy ,
This waveform is HO1 and COM. I add measure the voltage between VS1 and COM.
