I am designing a power supply that generates a half sine-like voltage with a shape and voltage is controllable by a microcontroller. The application is a master module
that generates a positive pulse for 10ms, this is used to charge capacitors of connected modules. The sinewave shape limits the inrush current of the capacitors.
After that period it should produce no power at all for another 10ms and disconnect. In that time the line is used for communication. Power is in the 10-100W range.
I thought of abusing a class-d amplifier such as the tpa3116 for this. I would drive it with a positive control voltage, so the chip would only generate positive voltages.
Would it be possible to use the chip in that way?
