    please check my buck converter in simulink

    I I copied the buck converter in the picture and turned the simulation around. But the resulting waveform was not what I wanted. Shouldn't a dc waveform of 7.5V come out? What's the problem What role do transformers, diodes, resistors, capacitors, etc. play on the MOSFET gate input side, and...

    Questions about Buck converter

    What is the role and purpose of the 470uf capacitor? Is it simply disconnected because it's connected in parallel with 330uF? And 5 pin out is 15V pulse or low pulse? What is the expected transformer ratio?

    LM2679-5.0 Switching Regulator Design

    I am designing a constant 5 volt output switching regulator that bucks 12 to 24 volts down to 5 volts while supporting 5 amps. It is used to boot up a Raspberry Pi with a 10 inch screen. At 12 volts, the Pi will boot up fine. At 24 volts, around halfway through the bootup, the regulator will...

    Buck Converter Simulation in Python

    Hey everybody, first time here! As a personal project I am implementing a Buck Converter simulation in Python. My basic idea is to give a constant Vs supply and simulate the switch on/switch off steps in each switching period, calculate the increase/decrease in inductor current and calculate an...

    Ringing on inductor current waveform (buck converter)

    Hi guys! I'm working with the power stage for a buck converter, but when I did some measures with the scope I saw thet my inductor current waveform has a thing that I think are ringing spikes. Of course this is not a perfect triangular wave like in simulations hahaha. Background: The green...

    Converting from 30v-40v to a higher voltage to decrease power loss in the cable...

    Powering a load situated more than 200 meters from the power source will result in huge power loss due to the wires resistance.... The load need 1.5A and the power source can deliver up to 3A max. Designing a boost converter at the output of the source before connecting it to the wire to step up...

    Buck regulator output capacitor via current sharing

    Hi, I have a question regarding Buck regulator output capacitors via current sharing. we have 12V to 1V @ 35A regulator design, which uses 7x100uF,5x150uF bulk capacitors, which are placed sequentially few on TOP and remaining are ON BOT layers with vias connecting all capacitors from TOP to...

    Designing power bank circuit with BQ24195.

    I want to design a power bank control board for a single-cell lipo battery. The IC I have selected is BQ24195 by texas instruments. I think it is perfect for what I need. It comes with charge control, boost, voltage protection, I2C control, and many other features. But I have some doubts about...
