Looking for ideas on a circuit to follow a HV battery voltage range from 90-130V DC and produce input voltage +50%
100V DC would become 150V DC
90V DC would become 135V DC
130V DC would become 195V DC
The output current requirements are very modest <2ma but it must track the input voltage and increase it by 50%
It will be feeding into an approx 100K minimum load..
Ideas?
I looked at doublers/multipliers but they require an AC or chopped input.
That might be doable if the output voltage can be controlled accurately enough by varying the pwm etc.
It's possible to buy a commercial unit see link but it looks expensive and tricky to get.
