The capacitor size came out to be approximately 1uF. Post as a guest Name. The value for 20kHz is 0.
No, create an account now. Jun 18, 3. So you can troubleshoot the circuit somehow? Should I use a 1uF cap. Jul 17, 22, 1, Do you already have an account? Infineon distances itself expressly from the contents of the linked pages, over the structure of which Infineon has no control.

Unfortunately, by looking at the suggested schematic see below I’m unable to understand what value should I be using for this. Jun 18, 4. Should I use a 1uF cap.

High voltage half Bridge mosfet problem.
The objective is to help you understand this new age technology and its benefits.
Post as a guest Name. From the application notethe expression to find the bootstrap capacitor is as follows. If it does then it is not due to cross conduction. Sorry, I’m about ready to leave for a couple of days. Jun 1, 95 0.
I just redid my calculation and the answer turns out to be the same. All postings and use of the content on this site are subject to the Usage Terms of the site; third parties using this content agree to abide by any limitations or guidelines and to comply with the Usage Terms of this site.
Does the capacitor need to be bigger than this in practice? Saad 2, 6 42 That’s for the 20 kHz side presumably. May 1, 33 0. The simulation however fails with overflow and convert error. Is there a disadvantage to using a larger cap?
