![]() Will it work?Īny responses would be greatly appreciated. ![]() My friend suggested to use CD4049 to the LO pin of IR2110 and use it to activate the gate, replacing the HO pin. At first, I used 0,47mikrofarad electrolytic capacitor for VB to VS pin on IR2110, as I read about bootstrap capacitors, I changed it to 1mikrofarad and it is still not showing the waveform output but the voltage is 25V, while I got the waveform output from the LO pin at 9,2VĤ. The following diagrams are designed to work as a 3 phase PWM controlled inverter from an Arduino. The high input and low input for IR2110 is from two pins of Arduino PWM output.ĭelayMicroseconds(x) //x is 62, to produce 8Khzģ. ![]() The H-Bridge consisted of 4 IGBT (IRG4PC40U) driven by 2 IR2110.Ģ. I'm trying to build a Full H-Bridge Inverter for a school project. I know there have been many posts about this issue but as I scroll them over, they're years old and I'm getting confused from reading so many threads.
