sir when you said that Vc will charge equal to Vs @7:06.. wont there be any voltage drop across R2 due to the curret flowing through it.. if there will be than Vc should be charged with Voltage less than Vs.. please reply asap.. Thank you sir!
nice work .... really u r great sir .. how hard u r working for the students the way you explained wonderful sir ... thank you so much for ur efforts .. even very weak student can understand easily all the concept #bestteacher
as we know time constant=RC. where R= equivalent resistance across capacitor together with short circuiting the independent voltage source and open circuiting the independent current source. now you can try yourself.

Class D called impulse commutation not the class C.
If I'm wrong please explain
exactly.. you are right..
this is also used in or this itself is called as "DC circuit breaker"
Sir at the beginning of 1st mode to turn On T1....T2 has to be OFF
Thankyou sir!! For making us better in power electronics

yeah but we are talking about steady state condition and you know very well what happens in steady state of rc circuit.
Here the linear charging of capacitor is taking place..but you have used the formula for exponential charging..
At t=0 T1 is on and it is shorted so voltage across the terminal T1 should be zero so why are we assumed T1 as a capacitor??

Very helpful video . THANK YOU ,SIR
Nice job..sir u're great !!
sir I don't understand why we are considering only one resistance for time constant calculation. pls explain
Time constant is calculated based on through which resistor the capacitor will discharge...in this case it is only R2
Sir, what about the waveforms?
sir class-c commutation ka waveform nahi ha kya
Sir , please upload the next videos of power electronics.
Brilliant boss.... Really nice to understand.... But show waveform as well
Wow sir kae bujhea
What will happen if circuit turn off time is less than device turn off time?
Then in this case the device will never off...means no switching action takes place..load is directly connected with source..got it..
@@GATEMATICEducation Ok sir thank you
why this commutation is known as impulse commutation?
sir please upload electrical power systems vefios
Sir
if possible plz make vedeos on inverter
sir I don't understand why we are considering only one resistance for time constant calculation. pls explain
LGF Temp For mode2 R1 and C are in series so T=1/R1C according to series configuration.
