Your name or email address: Unfortunately, by looking at the suggested schematic see below I’m unable to understand what value should I be using for this. Jun 30, Bookmarks Bookmarks Digg del. The objective is to help you understand this new age technology and its benefits.

From the application notethe expression to find the bootstrap capacitor is as follows. You May Also Like: Jul 2, You may need a more capable gate driver IC. Sign up or log in Sign up using Google. Apr 5, 18, 3, Posted by Runs in forum: Jul 17, 22, 1, Results 1 to 2 of 2. The value for 20kHz is 0. 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.

Too high and some FETs will start to turn on only ones wity very low Vth.

Is there a disadvantage to using a larger cap? But you applucation test the circuit with a load, as in an SMPS, many unexpected things can happen if there is no load. Infineon distances itself expressly from the contents of the linked pages, over the structure of which Infineon has no control. Home Questions Tags Users Unanswered.

That’s for the 20 kHz side presumably. Total gate charge for the IRF is 38nC.

Maybe you can try to turn 1 mosfet gate off first.

Try also the other mosfet. I have a boot strap circuit and have also charged the capacitor by giving pulse to low side switch first.

V Minthe application note states this is the minimum voltage between the Vb and Vs. How are the pulses at PB1 and PB0 arranged?

mosfet – Bootstrap Capacitor Selection with IR/3 – Electrical Engineering Stack Exchange

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. V Minthe application note states this is the minimum voltage between the Vb and Vs. If so, is there a rule of thumb saying how big? Pspice Simulation with IR The application note is clear on ceramic vs.

Jul 1, It will also provide accurate information about the principles behind quantum theory that helps quantum computing work. If it does then it is not due to cross conduction.

The capacitor size came out to be approximately 1uF. Hope I could help. Jun 18, 7.
