oost booster circuit
Duty cycle D= (vo-vi) \/Vo, where Vo is the output voltage and Vi is the input voltage.
From the formula, you can increase the voltage from 10V to 10000V or any multiple of the voltage.
In engineering, the duty cycle is generally not more than 0.9, so the engineering limit is about 10 times.
There is no more mature boost solution than boost, if you need a higher output voltage input voltage ratio, you can connect multiple levels of Boost boost.
