Unfortunately, by looking at the suggested schematic see below I’m unable to understand what value should I be using for this.

You should add your circuitry and the error report of your simulation about overflow and convert error to your post.

Is there a drawback to having a large bootstrap capacitor? Thank you very much.

Unfortunately, by looking at the suggested schematic see below I’m unable to understand what value should I be using for this. The value for 20kHz is 0. I aplpication unable to understand what is happening and would want some pointers and help to fix this issue. I just redid my calculation and the answer turns out to be the same.

Turn-off delay time is 42nS.

Jun 18, 8. Total gate charge for the IRF is 38nC. But you should test the circuit with a load, as in an SMPS, many unexpected things can happen if there is no load. From the application notethe expression to find the bootstrap capacitor is as follows. Your name or email address: Is there a ntoe to using a larger cap? That’s for the 20 kHz side presumably.

Could you tell me how much power you are using as your load? Jun 30, aplpication Email Required, but never shown. Jul 17, 22, 1, V Minthe application note states this is the minimum voltage between the Vb and Vs.

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.

Try also the other mosfet. I really don’t have time to go through all of this, but it sounds like you’re running into a cross-conduction problem due to insufficient “dead time”; and you’re running at some fairly high frequencies. Sign up using Facebook.

Am I correct that if I use a ceramic capacitor, this value would be value and therefore can be ignored in the above expression? 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 frequency of 50Hz.
