Is the ir2110 MOSFET simulation on LTspice working?
The simulation is now working fine. I had to reduce the boostrap capacitance to 0.022µF and LTspice provides me with satisfying results. Concerning the fact that the IR2110 does not work at 1MHz, the AN978 from IRF mentions that their circuits works at 500kHz (without noticeable heating). I found some project using it 700kHz.
How to use LTSpice simulation of H-bridge using ir2110?
IR2110sim .as is the point where it works. I am using ir2110 typical connection as guide how to connect it. Anyone knows what is the problem? I am using LTspice IV to simulate it. Could you upload the components as IR2110 and HCPL-2200? Could you upload the components as IR2110 and HCPL-2200? Click to expand…
How to simulate H-bridge with ir2110 MOSFETs?
I need to simulate H-bridge using ir2110 and irf540 mosfets. At some point in simulation, high output of ir2110 stops working, and I don’t know why, hope someone here could help me out.
What’s the maximum switching frequency for the ir2110?
Concerning the fact that the IR2110 does not work at 1MHz, the AN978 from IRF mentions that their circuits works at 500kHz (without noticeable heating). I found some project using it 700kHz. For the moment, I haven’t read anything explaining that it couldn’t be used at that frequency. My idea is to use at the maximum switching frequency.
Is the ir2110 based on an IRF application?
My design is based on an IRF application note (AN 978). _ at initialization, the IR2110 introduces a delay on the first pulse. But the frequency is followed after the first pulse. The design can be surely be improved and the configuration optimized (bootstrap capacitor value etc…). I would greatly appreciate a help !
Is the ir2110 a good HVDC gate driver?
The IR2110 might just scrape in thermally at 12V for the HVDC, but I have never seen a successful implementation above about 70kHz for HVDC > 100V, you will need to buffer the outputs if you are to stand a chance of it surviving thermally at > 100kHz… HVDC will be quite limited (12 to 24V) so my hope is that the gate driver will not overheat.
