Ir2101 three-phase bridge inverter

I found a 500W inverter implementation with an Arduino Nano and IR2101. According to its schematic, I think the input connections of both IR2101 are wrong. If it is …

0 I am building a half-bridge with IR2101 as half bridge driver and I am being confused by something in the datasheet of IR2101. My main supply voltage will be 40V. The …

Please explain how the bootstrapping circuit help in driving both the mosfets connected to IR2101 driver.Please explain this by taking an example of any voltage so that I …

I’m trying to make a controller with 3 H bridges (N-FET, IR2101 and a Arduino Mega). I’m sure that the problem is in my code but I don’t know how to fix it. I think that the …

I am trying to make BLDC driver with IR2101. MOSFETs I am using are IRFB4110PBF. So for testing I am currently using one pair. I am using oscilloscope to see the …

Do I need to provide galvanic isolation (optocouplers or digital isolators) between the Arduino and the IR2101 inputs? No this isn''t needed unless you have some specific …

Please tell me the use of high-side floating supply voltage (VB) and high-side floating supply offset voltage (VS) in the IR2101 (datasheet) driver circuit and also the use of …

The IR2101 is an high and low driver typically used to drive MOSFET half bridges. On this blog, it is said (IR2110 is almost the same as IT2101): "IR2110 can''t be used to drive …
