The views expressed here are my personal opinions, have not been reviewed or authorized by Infineon and do not necessarily represent the views of Infineon. One question though – suppose I require a capacitor of 1uF. Infineon reserves the right to make corrections, deletions, modifications, enhancements, improvements and other changes to the content and materials, its products, programs and services at any time or to move or discontinue any content, products, programs, or services without notice.

From the application notethe expression to find the bootstrap capacitor is as follows. Apr 5, 18, 3, That’s for the 20 kHz side presumably. I just redid my calculation and the alplication turns out to be the same. No license, whether express or implied, is granted by Infineon.

Results 1 to 2 of 2. Should I use a 1uF cap. Is there a drawback to having a large bootstrap capacitor? I have a boot strap circuit and have also charged the capacitor by giving pulse to low side switch first. The capacitor size came out to be approximately 1uF. The value for 20kHz is 0.

You may ir21133 a more capable gate driver IC. The capacitor size came out to be approximately 1uF. For what its worth, by assuming that I can ignore capacitor leakage current and Vmin, I used the above expression and the values I found for a applicatoon of 50Hz. Too high and some FETs will start to turn on only ones wity very low Vth. Quote of the day. Sign up or log in Sign up using Google. Pspice Simulation with IR The simulation however fails with overflow and convert error.

High voltage half Bridge mosfet problem.

Does the capacitor need to be bigger than this in practice? I cbs – leakBootstrap cap. Use of the information on this site may require a license from a third party, or a license from Infineon. Sign ir22113 using Email and Password. So you can troubleshoot the circuit somehow? Does the capacitor need to be bigger than this in practice? HelloAre there anybody experienced at high voltage half bridge?

If you follow the one shown above you WILL need a load, but if you follow the one shown below, you don’t need a load to charge the caps.
