Is there a drawback to having a large bootstrap capacitor?

I R 2 3 04 switch frequency: Total gate charge for the IRF is 38nC. 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.

Jun 18, 8. Could you tell me how much power you are using as your load? Bookmarks Bookmarks Digg del. Hi iamhere, In the diagram attached, I’ve shown two configurations for halfbridge circuit.

May 1, 33 0. One question though – suppose I require a capacitor of 1uF.

Too high and some FETs will start to turn on only ones wity very low Vth. I cbs – hoteBootstrap cap. The capacitor size came out to be approximately 1uF. If it does then cross conduction is highly likely.

The objective is to help you understand this new age technology and its benefits. Hello, What driver chip are you using? 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. Thank you very much. The application note is clear on ceramic vs.

Post as a guest Name. Jun 18, 3. I just redid ir21113 calculation and the answer turns out to be the same. Saad 2, 6 42 The datasheet states a minimum of 3. The value for 20kHz is 0.

Jun 18, 4. V Minthe application note states this is the minimum voltage between the Vb and Vs.

High voltage half Bridge mosfet problem.

Your name or email address: The application note is clear on ceramic applicstion. No, create an account now. Apr 5, 18, 3, Does the capacitor need to be bigger than this in practice?

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. Posted by iamhere in forum: Quote of the day.

But you should test the circuit with a load, as in an SMPS, many unexpected things can happen if there is no load. Discussion in ‘ The Projects Forum ‘ started by iamhereJun 18,
