my buck-boost does a short circuit in the time when its charging the inductor, and my supply source goes unstable. Can you explain me the reason of this please Sr. ? I learn so much with your videos.
it means you are switching it in overcurrent condition or it is being driven in Continues Conduction Mode try to reduce duty cycle or may be the gate is not being discharged properly so that the inductor is taking continuous conductor current
@@HaseebElectronics Thank you for your response Sr. I am working on mppt controller, and yes, i thought that I should do this project in continuous conduction mode, so would you recommend doing it in discontinuous conduction mode? i have a headache trying to make this. Your responses are highly appreciated
I really appreciate. Please I want you to explain deep on alternating current because I'm confused about the sine wave drawing of AC current or voltage. In our homes the main ac outlet if the socket have line(L), Neural(N) and protective earth(PE) and from the transformer station the Neutral is from the common point of the transformer Y connection down in side the ground. Now I want to know how current flow from line back to Neutral and the second phase from Neutral back to line even the AC rectification circuit diagram also shows that ac current can flow from line back to Neutral and from Neutral back to line for a complete cycle. Please kindly explain deeply
Please continue your videos they are informative and easy to understand. Mabe some info on power inverters and pure sinewave. Or mabe just how mosfets work in an inverter for high voltage or in an amp for high amperage.
I most ask you to do a video on mosfet types and igbt types because I never knew that mosfet or design in type higher frequency switching and low frequency switching because I try 10 different mosfets series number and brand I notice all irf design mosfets in low frequency won’t work at properly a higher frequency the mosfets heat up but at low frequency the mosfets don’t heat and I try the 75n75 mosfets that is rated for higher frequency and it don’t work well at low frequency the mosfet heat up at lower frequency only works well a any higher frequency and the hy4008 work really great at any frequency no heating up but when the voltage get pass 37 voltage it started to heat up so please tell us about this
I made boost converter and buck converter fly back converter easy but the buck booster converter is the most stressful one all my 60 amp ultra fast switching diodes is damaged and mosfets damaged I know how to build circuit properly the connections or right on design but the mosfets getting hot when booster and diodes blow out buck when I built buck converter and booster converter and joint the two together the circuit work more efficiently then the buck booster circuit no heating up I use only original mosfets from UT sources so the fet is good
I found a big error in your circuit I use this design with all 12 type of mosfets igbt 5 amp gates drive nothing work mosfet getting hot volt not boosting and in buck mood at 100khz the circuit refused to work I then I read my engineering design book the same issues I face the book motion that this type of buck booster is not always works the design for high efficiency is to remove the gound and use the diodes ato create a negative gound for positive and connected it the the capacitor that how I get the circuit to work very well and 6000uf capacitor not heating and a lot of power
indeed it is not a circuit, it is a very basic conceptual explanation about its working principle. while designing it needs too many parameters to be covered and it also have drawbacks it design, compensation and losses must be observed, calculated and compensated to have a proper working design. the most important thing is the magnetic design and the rectifier diode selection
Thank you for the Diagram and Explanation.
You are welcome
Emeğine sağlık kardeşim.Güzel video olmuş.Sağlıklı ve bol kazançlı günler dilerim.
Interesting Hope more exciting in the future 👏👏👏 God Bless you! 🙏
Very useful information 👌
Thank you for sharing knowledge
Good night 🙏
best regards
Very useful information sir thanks for sharing this knowledge to us
Most welcome
Ah, do you think I can use it as a split power supply to power an low current opamp in audio application? thnks for the answer in advance prof.❤

Thanks sir 🎉❤
Most welcome
Always wait for your basic tutorials. But at 2:27 is it not short circuit ?
👌
👍
✋
Good Job Buddy!
best regards
@@HaseebElectronics Your Welcome!
Because I want to use my scope to measure the DC voltage immediately after the bridge rectifier to avoid blowing up my Digital oscilloscope
kindly check this video and if there is any query, please let me know

Hello Brother
sir calculation of the inductor for buck boost converter
yes brother we will do it after completing topologies introduction
i will try to share in detail

Can you share the ratings of all components i want to build this circuit
