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). I am using PWM frequency of 16Khz , will this have any impact on the circuit working conditions. If so suggest me the PWM frequency along with the switching sequence i need to use
Regards,
Suresh
