hi im designing boost converter Vin = 2.7 and Vout = 45 V with Piezo cap. as load. Just now the efficiency is around 45-50 %. I also tried to use dynamic PWM, but i found that its also not much of use. timebeing im using 1mH inductor with DC resi. 2-3 ohm. and N channel FET controlled by PWM. in this design im very particular about power c
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 (...)

Hi, I need to control the output of a boost converter and make it equal to a given reference voltage. But I need to control my inductor current as well and make that equal to a given reference current as well. My input voltage is variable and so is my inductor current reference. However my output voltage has to remain constant. I need some tut
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
I am going to build a boost converter soon, just using the standard topology. however the last thing remaining to be determined is the inductor size. i can run the thing at anywhere between audio frequency and 100+ kHz, whatever works out best... but I don't know what inductor value to use. As far as I know, bigger is generally better, so
hi all, how to measure efficiency of boost converter ? as I know, efficiency= (Vo*Io)/(Vi*Ii), but should I use rms value, or average value of Vo, Io, Vi, Ii ? and what is the value readout from the meter ? rms or average ? thanks
Ok, so if anyone had read my post about needing a buck or DC-DC converter to power some 20-40ma 3.6v LED's: then they know my dilema... however, I figured I may be going about it all wrong and actually want to use a boost converter. The ones I've seen are the Badboy and the Wizard2. Would they be capabl

When i was simulating the boost converter,i found the power dissipation on the switch mosfet sometimes was bigger than the power source,and sometimes approximated to the power of power source,then the total power dissipation in the converter components was bigger than the power supply ,so where does this power come from? Is my simulation (...)

I would like to know if somebody has tried to change the diode of a inductor based DC/DC boost converter to a MOSFET working as diode. I have tried it but a lot of SOAC appear in the simulation using 0.35 AMS technology (h35b4, 50V tech). If it should not work, could explain why? The design has to increase voltage from 3V to 50V. There are 50V mos
