hey i am doing multi level inverter. in my project i use 4 MOSFETs (IRF460).
the pulse ll be given from MCU. i need driver for MSFETS . pls help me!!!!!!!!!!!

but i bought ir2110 high-low side driver. i confused to choose bootstrap capacitor.

 

You may find help by reading the section on bootstrap circuit design in this document: http://skory.gylcomp.hu/alkatresz/hip2500 an9010.pdf

 

hi jkrish,
Can u tell me the price of IRF460 , power mosfet which u are using?

 

i got for 1 usd (rs 50 india)

you can use two IR2181 MOSFET drivers to accomplish what you have just described.

 

A bootstrap capacitor of 5 times the gate capacitance of the driven MOS will be fine.
