Pspice Simulation with IR Half bridge induction heater mosfet problem Posted by ajrenzetti in forum: I cbs – leakBootstrap cap. Does the capacitor need to be bigger than this in practice?
It’s a long drive home. Jun 18, 6. Does the capacitor need to be bigger than this in practice?
Use of the information on this site may require a license from a third party, or a license from Infineon. So you can troubleshoot the circuit somehow?
If so, is there a rule of thumb saying how big?
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. Jun 18, 5.

Jun 18, 1. The objective is to help you understand this new age technology and its benefits.
High voltage half Bridge mosfet problem.
The capacitor size came out to be approximately 1uF. Post as a guest Name. Infineon distances itself expressly from the contents of the linked pages, over the structure of which Infineon has no control. Is there a disadvantage to using a larger cap?
Unfortunately, by looking at the suggested schematic see below I’m unable to understand what value should I be using for this. Jul 2, Sign up or log in Sign up using Google.

mosfet – Bootstrap Capacitor Selection with IR/3 – Electrical Engineering Stack Exchange
For what its worth, by bote that I can ignore capacitor leakage current and Vmin, I used the above expression and the values I found for a frequency of 50Hz. Total gate charge for the IRF is 38nC.
Could you tell me how much power you are using as your load? Thank you very much.
