Good video you are a very good teacher another topic I would kindly ask is washing machine main boards am having problems with outdated models is it possible to repair them with all the silicone on them?
Thanks my Friend for all your good vidéo. I have a 1500w pure sinus inverter but is out of order because of my solar micro tie inverter turn on in the same time of my 1500w inverter. Where do you think the problem is. The primary looks like ok. Good voltage. But nothingnon the secondary, the main 450v condesator stay to 0v. Thanks a lot for your help
Fascinating. Have five inverters, each behaving differently. This helps me investigate what went wrong. Very timely 3-part series....can't wait to learn more. if this unit you are showing us fails easily is there something we can do to improve them, or just best to avoid them ? Looking for better power management.
Salamu alaik brother. Please do you have the whole board schematic? If not, do you have very good quality pictures of the board so I reverse engineer the board totally?. I need to know how exactly everything is done .. specially the feedback and the microcontroller part. Please let me know if you have it. Thanks.
like #110👍😍 Walaikum’Asalaam brother. Masha’Allah very nice video great sharing as always very informative and helpful upload. great work great knowledge Masha’Allah. thank you so much for sharing your amazing skills with us stay blessed bro 😍👍💐
I have a samlex 1500 watt inverter that will not drive the transformers,removed transformers and drive circuit works.have tested transformers,they test good.do you have any idea what else I can test?
Sir , goodmorning. You are explaining very nice as usual. Sir i wish to know when we are connecting MOSFET some time there is explosion so how to prevent using oscilloscope.I wish to check driver circuit with oscilloscope befor connecting MOSFET. Same thing I wish to know in VFD. Thanks and regards connecting MOSFET.
I have 24 v to 220 v inverter....it was working well...suddenly it cant drive a 750 W water pump and over load indicator turns on...(may be low amp output...can you advise please? Thank you
I alway enjoy your content but my question is why mosfet alway burn 🔥 up in inverter and the overloaded protection is there to turn of the pwm signal so how is that the mosfet still short circuit I don’t understand this in commercials inverter because I built my own inverter and overloaded it and the overloaded TC transformer shutdown the ic and mosfets never blow out I try this over and over and the protection alway work so is that I build a really good inverter or what
wow that is really great achievement mosfets burn out due to many reasons 1. push pull switching topology (i will explain in upcoming video) 2. material failure 3. hard switching 4 allocating low dead-time for both channels
Please sir, I request you talk about the windings of the transformers. In as much as the primary side is in parallel and secondary side is in series. Thank you.
Assalamualaikum warahmatullah. Engineer please put me true on how to reduce the frequency of this inverter you are explaining on, from 98hz down to 50-60hz. Please.
what if we add a bridge rectifier so that irrespective of the polarity of input 12DC voltage, the polarity of 12V feeding to the inverter may remain same and it does not harm the circuit.
Salam Alaikum Haseeb. For Allah's sake 🙏 My 2KS-12v-2019 OneWorld is 2000p inverter just like your 3kva. I need your guidance to know why it starts fluctuating after working for like 30 minutes, let it rest for 5 minutes, turn it on work for another 30 minutes and starts fluctuating again. Please guide me in the name of Allah 🙏🙏🙏 Thank you in advance.
you have to study the design. in some pure sine wave inverters this current is normal. if you will add some inductor, these inductors will become another load at loaded output. so it will cause to drop output and will lower the effieciency of the converter
I have always heard to step up or step down we need a transformer. But I don't understand how the output switch step down voltage without a transformer.
output switch just changes the voltage polarity on output line to get frequency to boost voltage from 12 to 350-400 volts, the voltage booster stage is used. it have a step up transformer
No bhai basically i am from Pakistan and Now in Jordan you can check my check my Urdu channel (haseeb Electronics Urdu) as well to watch my videos in Urdu Language

sir, Kya Aisi SMPS ban Sakta Hai jis Se 220 Volt out put nikal Sake 2kW use ke Liye like as a Stabilizer
Salm sir .. sir is chotay pnp dono transistor ka kia paida hoga sir
நன்றி sir🤗🙏
special thanks
Pls can I change all the MOSFET in inverter since I did see the same one that came with it
Salaam sir one question you multiply 330v to .706 what is that 707 ?
when it provides switched voltage in output it is peak voltage
to convert peak voltage into RMS voltage, we have to multiply with 0.707

Assalamualaikum warahmatullah. Engineer please put me true on how to reduce the frequency of this inverter you are explaining on, from 98hz down to 50-60hz.

how can we add an out put voltage selector? for 110 or 220
what if we add a bridge rectifier so that irrespective of the polarity of input 12DC voltage, the polarity of 12V feeding to the inverter may remain same and it does not harm the circuit.

Hı my online ups 1000kva true sine no load current is very high 1.7 amps . Can i reduce no-load current with inductors ?
you have to study the design. in some pure sine wave inverters this current is normal. if you will add some inductor, these inductors will become another load at loaded output. so it will cause to drop output and will lower the effieciency of the converter
Thanks sir
So nice of you
May I have the link to your video of H Bridge Switch Topology.
still i haven't discussed H bridge switching topology. i will try to explain it soon
why 1000w power inverter have current on both terminals? how can i connect this inverter with single inverter wire
I have always heard to step up or step down we need a transformer. But I don't understand how the output switch step down voltage without a transformer.
output switch just changes the voltage polarity on output line to get frequency
to boost voltage from 12 to 350-400 volts, the voltage booster stage is used. it have a step up transformer
@@HaseebElectronics and to step down from 350-400 volts to 220-240? How does out put switch do it?
Sir, are you from India ?
No bhai
basically i am from Pakistan and Now in Jordan
you can check my check my Urdu channel (haseeb Electronics Urdu) as well to watch my videos in Urdu Language
How can you calculate the number of mosfet use for inverter
How can i learn from you?
you can follow my videos
What is the actual wattage of this inverter
Are you graduated from uet ?

@@HaseebElectronics AOA sir
I glad you replied my comment.
I have question it will be very kind if you answer me.
The question is that electronics is my hobby and I am designing circuit board since my childhood and now I am professional in this field,my age is 17 and I just passed my intermediate exams (ICS)
I always wanted to get admission in electronics field or in electrical engineering but sadly ☹️ universities are not giving me admission in these field,they are saying we need a student who had studied chemistry in inter but you had computer in your inter so you can’t take admission in electrical engineering
But they are offering me CS(computer Science 4 years 8 semester BS),so as you are such a brilliant engineering and my hero in my hobby field (electronics),so would you recommend me to go for computer Science or not?
My subjects in inter was computer maths physics and I am expecting 90% marks in inter exams ...
Mathematics physics and electronics is my love and I also like computer.
What do you think will I become a successful person in future if I go for CS?
@@saminaanjum9429 Good to know that you have a deep interest in electronics
in intermediate you selected computer science so now you have to continue in same field.
or if you want EE then you have to proceed to Intermediate pre-engineering.in this case you will spend 2 more years then in engineering.
it is best if you find CS chance, CS have also a bright carrier in future.
i will suggest to continue in computer science
wish you best of luck and huge success in every field of your life
