Could you please explain me how does it reduce ringing. To reduce ringing only we have Gate Resistor right?
It is used in most of the circuits when use MOSFET as Switch and also operating at higher frequencies
Hi,
Why there is an capacitor or resistor+capacitor is added between Gate and Drain of the MOSFET when MOSFET is used as Switch. IS it to improve Thermal Behavior. Anyone know about this
Dear Malli,
You r wrong. I also was thinking like that only. but parallel combination only gives me the correct result(Simulation). But i don't how these two resistor in paralle because both resistors r connected at different battery terminal
Thanks & Regrds,

HI
How can you considering two resistor in parallel (C*R1*R2/R1+R2). because 1K resistor terminal is connected with positive supply & 10K terminal is connected with negative terminal.
Hi All,
Please any one can tell what is charging and discharging time constant for the attached circuit. Please give some explanation
Thanks in advance.
Thanks & Regards,

Re: Reg:Boost Converter
Thanks for your reply.I can really understand that. Is there any other constrain other than efficiency ?Any mathematical relations like upto some duty cycle only it can operate-able (Boost converter will be efficient) .Hence only X times of input voltage can be produced...
Dear All,
How much times of input voltage can be boosted at the output of boost converter. For example 10V can be boosted to 1000V? or 1V can be boosted to1000V? What are all the limitations? Losses will be more due to high current? Is there any limitations in the duty cycle and operation...
Dear All
I am working as Embedded hardware Engineer..I am from india...I am interested to attend EMI/EMC training. What are all the organisation gives this training in india..Which is best..
Thanks in advance

Hi,
Is there any application notes which explain about relation between gate resistance and rise time,turn on delay etc.,
How to choose gate reisitance for perticular application?
Sakthi
Dear All,
What are all the factors should be considered for selecting gate resistor for MOSFETS? Is there any formula which relates rise & Fall times and gate resistor & capacitor?How do i calculate Rise and fall times for perticular gate reisitance?
Thanks in advance,
Thanks & Regards...
