Thanks you very much, i have use the formula to design my boostrap circuitry and I am trying now to simulate it on pspice. For 24V DC BUS, with 15V VCC, 500 kHz, 10A, using a MOSFET IRLU3410 and a diode MURS120T3G I found 2uF - with a x15 factor included)
I have another question : At 500Kz, with a 50% duty cycle, do I need to add some dead time on the HIN/LIN command (full bridge - 2x2110 and 4 MOSFET ILRU3410) ? If yes, how much do you think I need to use ?
Thanks again !
