Thanks you so much for mppt video series, It helps me a lot for my bachelor thesis!

Informative video. Have watched a lot from this playlist and really helping me in my project works. But how do I calculate the values for the inductor and capacitor and how do I select the components for the boost converter while designing?

Question,... if you put an inductor in series with the imput of the boost converter, will this increase the input impedance?

for a pv panel do we have the value of RT? the final equation RT= RO/D*D help to give the range of D for the application? if is the case how?

Isn't output voltage governed by Ohm's law Vo=IoRo?

11:12 I thought the discharge of current is exponential. How do you write it as -io(dTs)? What are the assumptions? Am I missing something?

@vaibhavgarg1982 3 жыл бұрын

You are right. However, the switching is done at a high enough frequency such that the time for discharge is very small, and the part of the exponential curve in the small time can be approximated as a straight line.

Why is the voltage across the inductor zero for one period Ts? What is the explanation for this?

@ChandrakantVadher 3 жыл бұрын

Under steady state, the average voltage across the inductor over one switching cycle must be zero, else the current would keep on rising, which can saturate the inductor. So for inductor volt-second balance must hold in steady state.

its because when you apply periodic current through the inductor the current value is same at the end of each period leading to average value of inductor voltage become zero...Integrate inductor voltage over a period you would get current but as the change in current is zero that integration becomes zero..fyi integrating over a period is essentially average value of that function

At 7:17, why Vo > Vt?

@vinayakpb6012 2 ай бұрын

Considering it as a Boost converter (Vo>Vt).

@@bonds3865 In case of Boost converter output voltage is greater than input (hence named as boost). Vo=Vt+Vl during off time of the switch, (i,e inductor discharges the stored energy to output at this time, so denoted as negative voltage at off time)
