choosing mosfet for my buck boost

the "elephant in the room" is why a buckboost and not a buck....or rather , interleaved buck as above said - - - Updated - - - I presume it is a 4 switch buckboost or three anyway you get 2 diodes with reverse recovery in them instead of just one with a buck. However, The reason to do buck

Power stage small sighnal transfer function for current mode CCM synchronous Buck?

In a first order estimation, the modulator and power stage transfer function of a synchronous buck or boost converter is current independent. Use CCM equations.

buck-boost converter in dcm mode

hi i need help in buck-boost converter in dcm mode: 1.I want to solve exercises of this converter(in dcm) so I search questions and solutions - because it's easier for me to understand things through exercises , So if someone please could send me it would be nice. 2. How I calculate switching losses and conduction losses in MOSFET and how

For designing DC DC boost converter

hi all, i do my project as design of DC-DC boost converter . In that, how to calculate the L and C.. if it has any equation means send to me quick. Thanzzzz.

DCM transfer functions of buck/boost

Hello! The problem I've faced is the following: I need to analyse the stability of buck and boost converters operating in DCM, using the traditional Bode plots, based on the transfer functions of these converters. Searching through books and articles, I've found several DIFFERENT equations for the transfer functions of mentioned converters in

Question:regenerative braking in a traction motor

I guess you'd begin with determining the motor output voltage (RPM and constant) and the boost ratio to get 600V + delta (diode drop, series resistance, braking current) which with an assumption about converter operating mode (conduction) ought to get you a duty cycle from boost converter basic equations. Treat the motor as a voltage source (...)

hi-isolated boost dc-dc converter help..

51084 I am designing an isolated boost dc-dc converter..for Vin=250V and Vo=400V and calculating n from equation (Vo/Vin)=n/(1-D)..where I am taking D as 0.5..but not getting the required result as 400V. L and C are designed using the equations from boost converter design. I have atttached capture 2 my design....

Equatios for DC-DC converter..Boost Converter...

hi all, can anyone provide me the equations for boost Converter?The equations for finding out L,C? Thanks a lot....

Boost converter equations

Thank you for the answer. I don't use any output filter in order to keep bandwidth capability of the boost converter, tha's why I need to optimize the output ripple according to L & C values.

Mosfet current in Boost converter

Hi guys! I need some theoretical help with a boost converter. I need to know the (aproximate) average mosfet current in a boost converter. Let's say we have 10V input, 40V output voltage and 1A output current. I need only a rough estimate of what the mosfet current would be. Any ideas how to calculate this? Best regards!

Info about calculation of boost regulator component values

Can someone give some information on calculation on boost regulator component values? e.g. the inductor, diode, in/out-put caps?? Thanks.

Statespace conversion to transfer func. for boost converter

Hi How can I obtain a transfer function from a state space representation when this representation is non-linear. I'm trying to obtain the transfer function of a boost converter. I've obtained the state space equations using inductor current and output voltage as my two state variables under the two different switching conditions. (One in which

Equations for calculating circuit values of boost converter

Hi, I'm trying to step-up a dc voltage from 12V to 340V dc using a 3-stage boost converter. Does anyone know where I can get the analysis/ equations for calculating circuit values of a MULTI-STAGE boost converter? Are the equations different from that of a single-stage boost converter? I would appreciate (...)
