Photovoltaic Capabilities of LEDs
One of the follow-up questions on optocoupler bias generation was if optical LEDs would be a decent candidate for generating a higher voltage output without needing to handle the 8+ volt output from the isolated gate driver photocouplers. The short answer is no, probably not even in comparison to stacking multiple 0.5 V output optocouplers. Energized green SMD LED driving another unit of the same part number
