Hbridge using IR2110 not working at 220V DC

Hi,

we are implementing a DC motor speed controller using Full H bridge and IR2110 drivers.

The circuit works good for 12V , but if we wish to control a 220V DC load the circuit is not working.

The high side drivers (S1 and S3) of 2 IR2110's are always ON, eventhough we give inputs to S1 and S4 (forward direction).

Gate resistor used is 10ohm and boot strap capacitor of 1uf/10uf is used.

Please help me solve the issue, why at higher DC voltage the circuit is not working

Regards,
Suresh

One more point to add, the same circuit if tested in half bridge configuration works fine at 220V DC .

I am not able to figure out the problem, please hlep

I am using a PWM frequency of 16kHZ

I am attaching the circuit please check and let me know what wrong did i do, and whthe circuit is not working for 220V DC

have a look at this link if it helps..
