high side

I am using a IR2101 gate driver circuitry to switch the high side IGBT ON (I do not want it to be periodic). Hence I found out that since I am not frequently switching the IGBT, the bootstrap circuitry doesnt not work since the capacitor cannot charge up. I therefore found out 2 ways I can...

Hey There, so looking into Optocouplers, I just realized that the output is a transistor controlled by the light from the input - I (for some reason) thought it was a voltage source like a solar panel. Anyways, this would have funny, maybe stupid applications, like generating very high...
