i have a question in ir2110 ic n channel high side switch using bootstrap operation does Hin and Lin are supplied by the same pwm at the same side and the inverted signal for the other side
or
the pwm is set to Lin and inverted to the Hin at one side and at the other side the same lin and its inverter signal also

"i know about dead time"
datasheet http://www.irf.com/product-info/datasheets/data/ir2110.pdf
application note http://www.irf.com/technical-info/appnotes/an-978.pdf

 

Hin and Lin are supplied by the same pwm at the same side and the inverted signal for the other side

No. The high-side is on when the low side is off. The bootstrap capacitor is charged through the low-side switch.

lower power switch ON = bootstrap cap is charged
upper power switch ON = bootstrap cap discharges into the gate of the upper switch

do you mean that the LIN is inverted to Hin?"dead time is concerned"
if so how about the Lin signal to the other side "the pwm is set to Lin and inverted to the Hin at one side and at the other side the same lin and its inverter signal also" is it the second choice

 

Imagine a H-bridge.

The PWM for the upper left and the lower right switch is the same.
The PWM for the lower left and the upper right switch is the same.

The PWM of the lower left and upper left and the PWM of the lower right and upper right are NOT the same. You can not turn on both switches of the same leg at the same time.

EDIT:actually, depending on the type of modulation, the PWM of upper right/lower left or lower right/upper left does not need to be the same. They need to be on at the same time at one moment though. So you can work with 4 completely independent signals if you want. Just make sure you never turn on two switches of the same leg.
