Hello,
I want to regulate my boost step by step, for this I need to control the voltage that the inductor can induce to the capacitor. For example, if I want a step of 5V, I want my inductor to deliver a voltage of 5V (+ the supply) to the capacitor.
So, I tried a simulation (attach file below) with that kind of parameters :
There is only 1 pulse that lasts 1 second.
During the pulse, I have a current of ~1.66A, so if I made the equation of the voltage:
V = L di/dt = 1* 1.66/1 = 1.66V
But when the pulse turn off and the inductor start discharging (charging the capacitor at the same time), I got a very high voltage across the capacitor:
The voltage across the capacitor goes up to 100V which is not what I want. I wanted here to have a step-up of 1.66V per pulse...
Does anyone know why it doesn't work ?
