This one v out is the output voltage equation and vs is the source voltage and d is the duty cycle. So the questions are study, study, study, electronics, boost yep, so our output voltage equation is uh supposed to be here somewhere yep. We are having about yep, it is almost stable, like 20 volts, we can further increase it and the more we increase the duty cycle, the higher the output becomes okay, so we have some equations which can give you the exact amount of inductance and capacitor. Let us increase the duty cycle to 25 percent. So we are having about 17 volts from a 15 volt supply. This caused it to become much higher and now it is gradually falling and stabilizing. I think it was an initial injustice from the inductor to the capacitor. Okay, we are seeing actually 33.5 volts output. We can further stabilize it by using a capacitor this wire, capacitor c ground reset. Here we are seeing that we have a something edit show rms rms voltage. It would be perfect, and now let us let us take an ideal diode make it almost ideal by using forward voltage one millivolts almost ideal, and it seems we are good to go and reset uh. So we what else uh, let the inductor be about one milli henley. Okay and what else wait? What oops dc offset 0 frequency? Okay. We can tune the r sorry we can set the arduino unos uh timer, zero to oscillator at maximum 62 and 500 hertz, and let the duty cycle be what 10 percent for now. I want a microcontroller or an oscillating circuit or pwm compared to whatever you want. Arduino is a microphone whatever you want. This pwm will come from an arduino or microcontroller. Okay, so here we will provide the pwm signal. This terminal would be connected to a strong source, but it is totally insignificant. It is almost insignificant, but still little significant in case of weight. Uh hfe 1000 regis store im using this ground resistor for actually not any significant purpose just for leakage in simulation, you dont actually need that and the magnitude be 100k. So this is our basic concept of boost conversion and now let us replace it with some realistic usable devices and because we cant toggle the switch this much time so im using an npn, npn, transistor and Music connect it up. Actually, we will use much lower okay, we are seeing that the current is gradually increasing, increasing increasing and if you open, the circuit same amount of current tried to flow and which cost to generate about 12.364 kilovolts here for a big period of time. Okay, so what was the magnitude of current for and it is very low? Actually, i want a bigger amount of current so for the simulation so for just making understand the circuit uh im using a 50 milli henley. What load voltage test point output test point: we will use scope okay, so when i open the circuit well see the current destroying from in this path. What im saying is that it will push the current yep okay, so let us simulate it uh! Okay, it is going way too fast and i want to see what this one current inductor current. It will pull the electrons from here to so. Even when this voltage is higher than uh the inductors, so source voltage still, it would push the electrons there. So, even when the this path is closed, it will take a higher uh higher resistance, but to complete that current amount of soil to flow that amount of current and by this virtue we are utilizing a boost conversion increasing the magnitude of voltage. So basically, what happens is that the inductor stores energy in the form of magnetic field. It cant go from here, so it will go over the diode and load. Okay, the path is complete, so when the switch is closed, this is the part of the car that the when switch is open. So it needs a part to push the current uh, so we place a diode and a load resistor here. Sorry, the inductor still wants to continue the same amount of current through it. So when this switch is closed, the current starts going from the 15 volt source to the ground uh and when the switch is open, the still the same amount of current wants to continue. I will later replace it with a bipolar adjustment, transistor bt. What is this called context? Menu will come up and you can see that what are the components that you can draw in the passport link keyboard shortcuts? Okay, so im now adding an inductor, uppercase, l and then, in order to complete the circuit, i am using a switch for now. You can right click anywhere and this uh. Uh 15 volts im using the keyboard for cars. This is the second single terminal voltage source. First of all, we take a single terminal voltage source but undo. So, first of all, what is a boost? Converter circuit boost converter circuit converts a low voltage dc source into a higher voltage dc source.
