Problem with IR2110

[stoyanoff]

I`m trying to control 2 IGBT transistors with IR2110. I`m using the chart from the attached file and have a problem. On HO I have +around 9V and doesn`t change on any compibination of input signals. On Vb i have the same potential. I think the LO is working properly.I haven`t connected the IGBT`s to power supply because I`m afraid of "Kaboooom", if i open the both transistors. Can anyone tell me where is the problem, and how to fix it???
Thanks!!!
