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

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

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 (...)

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.

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?

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 (...)

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 (...)
