Explanations are wonderful and I'm sure a lot of students are getting help from these videos. But almost all videos have some serious mistakes. For example, Supply is DC and the inductor in this case of DC just behaves as wire. I'm still confused about how the inductor is getting charged
But , brother according to the property of the inductor ( it allows DC and it blocks AC) it starts charging naa😊. I have silly doubt during T-off how output voltage will zero, I'm little confused. I think due to freewheeling diode , the entire load drops at diode.
Sir..what is the major difference in between buck converter and step down chopper?? Why we are placing a capacitor in buck converter but not in step down chopper??
In The step up chopper circuit the inductor is connected to the source before the switch but why does current flow through the inductor only when the switch is ON?

Chopper is a device that converts from constant dc input voltage to variable dc output voltage. You know if input and output will not mark so the totally answer was not complete.
In step up convertor, when switch is on, still diode is forward biased, so why current does not flow through diode and is restricted to inductor and chopper loop??
Engineering Funda sir pls explain about single phase full convertor with r, rl and dual convertor and 3 phase full converter sorry for big list thes question are too difficult so only 😅😅😅pls if u could explain about those 😊😊😊and thanks for these vedios very nice all the best for upcoming 😊😊

Sir why not diodes is connected to source to avoid reverse flowing of current and Why i1 and i2 for current Why not i0 to i2 Whether it means that there is some current already available please clarify
How u make supply curent varying,as it is constant dc current.morever how the polarity of inductor change,bcoz supply is same during turnon and turnoff.reply soon sir

@@EngineeringFunda thanks sir🙏🙏 Another question sir, what will be the voltage across the switch(MOSFET) Will the switch ever see voltage higher than the input voltage( self induced EMF)??
Actually I am designing a boost converter that can power a 9 watt 220 volt LED bulb from a 12volt battery. Again, sir thanks for sharing your knowledge with us🙏🙏
In Muhammad rashid book , in step up converter having RL load they have used an battery on load side ,...Sir ,what is the significance of that cell..... Please explain...... and value of E must be greater or smaller ?

Sir..what is the major difference in between buck converter and step down chopper??
Why we are placing a capacitor in buck converter but not in step down chopper??
Aseem ne bta diya bhai 😌
Great explain ...but take good video
Are step up and step down choppers same as class A and class B choppers?
Bhaisab..i thing you have compared the avg Vo of step down chopper with Toff Vo of step up chopper. Can you please clarify.
Why polarity of inductor changed when t off ?
In The step up chopper circuit the inductor is connected to the source before the switch but why does current flow through the inductor only when the switch is ON?
Thank you sir

Sir in step up chopper ..... during Ton why the current doesn't flow through the diode ???? please give me reply sir
Can you explain how to find the value of RMS value of Output voltage in Stepup Chopper
Sq. Root of D * Vin
Why the current when the switch is open still goes in the same direction? The polarity did not change?
Chopper is a device that converts from constant dc input voltage to variable dc output voltage. You know if input and output will not mark so the totally answer was not complete.
in DC supply power is constant . but how u got wave forms ?? are they ripples ? .
In step up convertor, when switch is on, still diode is forward biased, so why current does not flow through diode and is restricted to inductor and chopper loop??
How is the voltage across load 0 in case of Toff when their is current passing through the load by the Inductor?
Same doubt how is this possible???
Sir is this equation are enough to gain marks??? Pls reply sir
Yeah ,😀
Engineering Funda sir pls explain about single phase full convertor with r, rl and dual convertor and 3 phase full converter sorry for big list thes question are too difficult so only 😅😅😅pls if u could explain about those 😊😊😊and thanks for these vedios very nice all the best for upcoming 😊😊
Sir,in step up chopper when switch is on(t-on) why the current is not flowing through the diode (d) while it is in the forward bias?
current flows through all paths in an amount inversely proportional to their resistance, so it takes the path of the least resistance.
excellent

Sir do the vedio of
problems on chopper
Isn't this the same as the buck/boost converter?
Sir why not diodes is connected to source to avoid reverse flowing of current and
Why i1 and i2 for current
Why not i0 to i2
Whether it means that there is some current already available please clarify
In step up chopper...,
Why inductor is always charge when switch is on and...discharge when switch is off
If loop is enclosed then inductor will get charged by supply and if supply is disconnected due to switch off then in other loop it will discharge
But supply is still connected in stepup chopper ,during toff???so why not inductor current only increase
TAMIM SHIKTO : no it's wrong. Output is across diode so when diode is ON, output is zero
It's basic property of inductor
How u make supply curent varying,as it is constant dc current.morever how the polarity of inductor change,bcoz supply is same during turnon and turnoff.reply soon sir
Because of switching current and polarity of inductor is varying
if the polarity of the inductor change y the current direction is same
sir since the input is a dc voltage the how can inductor get charged ???
In simple language, chopper is the device which converts constant DC voltage to variable DC voltage. 🙏

Thanks Sir Ji
Can I step up 12v dc to 220v dc using chopper???
Yes but current ratings will go down.
@@EngineeringFunda thanks sir🙏🙏
Another question sir, what will be the voltage across the switch(MOSFET)
Will the switch ever see voltage higher than the input voltage( self induced EMF)??
Actually I am designing a boost converter that can power a 9 watt 220 volt LED bulb from a 12volt battery.
Again, sir thanks for sharing your knowledge with us🙏🙏
It's not that simple to reply without watching circuit
In Muhammad rashid book , in step up converter having RL load they have used an battery on load side ,...Sir ,what is the significance of that cell..... Please explain...... and value of E must be greater or smaller ?
+Eshant Jha : battery is used due to inductor which generates back emf and to nullify back emf bettery can be contacted.
Sir also it's written in no load when battery is used ..It should satisfy...0
+Eshant Jha : E can be decided by calulating reversal of current, generally it happens due to inductive element and impedance mismatch
Sir ias me scr nhi laga hota hai
You can use it
When the switch is off how the output voltage becomes zero because at that time inductor is act as a source and current is passing through the diode.
Ita tor voltage er iccha he je samay chaibo ui samay zero hoibo
@@subhajit9249 bal akta tui
At 10:42 why current is not started from zero??
Sir,how can we say this is step down chopper,as output voltage at "T"on instant is Vs only,it's not at all changing,then why step down?
Thank you,sir
I got it sir.....Avg o/p voltage..
In step down how output current increases when the switch is on ?
+varinder singh : it is charging inductor and as inductor is getting charged it allows more current to pass through it
+Engineering Funda : Yes off course current will increase as switch is ON
What is duty cycle??..sir answer please 🙏🏽

In the step up chopper circuit when the switch is off why is the load current similar to the current flowing through the inductor?
one question sir, during Toff the current doesn't stop flowing through the load then why the output voltage graph vo is shown off??
Output is short-circuit
but sir the output current passes through the load or the resistor......then accroding to v=i*r certain voltage drop must be there....isn't it??
sir kindly notice, i told about the case of the step down operation, not the step up operation
TAMIM SHIKTO : output is across diode, so when diode is ON voltage is zero ideally, practically 0.7 for SI diode.
thnx sir, can i have permission to contact with you in any social media..???
Sir how the output voltage is constant during on cycle even though the circuit acts as RL circuit
Using high value of inductance, we can make it constant
Very well explain use of colour pens is really helpful cleared concept thank you sir..
