[@rkbharate]

thankyou sir....
please make a single video on brief introduction of all the power electronics devices and this family members.

[@rupeshraikwar5801]

thanks sir ji

[@pawankumaratal6375]

Nice sir .. please fully revised method detail in gate triggers types

[@treserandtrailer6551]

Good sir

[@EngineeringFunda]

Your welcome

[@manjeet.x]

Thank you sir🙏🙏🙏

[@P3RYYY]

GATE TRIGGERING AND LASCR ARE USED BUT FORWARD BREAKDOWN VOLTAGE(HIGH VOLTAGE), RISE IN TEMP. AND CHANGE IN V ARE NOT PREFERABLE BECAUSE THESE METHODS CAN DAMAGE SCR.

[@duttadrj]

Some doubt regarding dv/dt method

[@harshaljindal5204]

sir can you provide some detailed explanation of dV/dt triggering

[@taylanozen3673]

Please sir could you explain what happen when dv/dt increase ? Best Regards.

[@UmarFarooq-yp5ym]

To scr trigger, can we give current to gate by 1.5volt cell (AA Size) directly. Or tell may it safe??

[@vangalasaiprasad6162]

explain Single phase half wave controlled rectifier with RLE load

[@shivamsaxena0255]

make video on voltage and current source inverter

[@rajgandhi4042]

How conduction period can be controlled by varying the gate signal?

[@duttadrj]

Sir before which part we derived IA CURRENT PLEASE PROVIDE LINK

[@vy_0076]

video no 9

[@kabandajamir9844]

How can we use triac without diac

[@EngineeringFunda]

In AC switch control we use TRIAC without DIAC.

[@saiganesh6325]

What are the circuits for gate triggering

[@SK-sl8oo]

Fet controlled SCR .....please explain this

[@arbazahmed9987]

sir what about power conditioning ckts (ac voltage controller)

[@aleemabbas5466]

dose high dv/dt mean high frequency ?

[@EngineeringFunda]

Yes. It means high frequency components in given signal

[@Simran_Kodere]

Engineering Funda how high frequency component explain?

[@sanyammaheshwari7575]

Sir please add numerical

please share the video number in which the derivation was done

[@duttadrj]

Sir please provide power systems lecture series also

[@sudipbiswas4718]

Sir I can't understand dv/dt method completely

[@bharatmunde6169]

Explain GTO

[@EngineeringFunda]

It is there in my playlist

[@b.sandeepkumar6456]

Is dv/DT is max voltage?

[@PhoenixiaMystique]

sir as alpha is inversely proportional to the emitter current, but when we increase the tempr , anode current inc. which is equal to emitter current,sir can u explain how?

[@b.sandeepkumar6456]

Sir please say difference between
Dv/DT and forward bias trigg

[@EngineeringFunda]

dV/dt triggering does triggering due to hot spot.

[@dgaurav100]

for Vin>Vfbo how much extreme voltage we need to provide to turn on the SCR in High voltage{FWD Voltage Triggering}..??

[@EngineeringFunda]

For highest forward break over voltage you will have to see datasheet of SCR. There are different SCR available so one needs to accordingly.

[@chandramouligunda7201]

Thank you sir
