Wkwkwk dunia dlm berita ya, berarti kita sudah pada tua... Mungkin lebih tepatnya tayangan "Hasta Karya" sangat menginspirasi sy pd saat itu👍. Terimakasih TVRI🙏🙏🙏
master arduino... , request MPPT solar carge controler , with EEPROM to costum setting, with pushbutton .. sangat aq tunggu mas karna pingin buat projek ini , trimakasih
Alat/rangkaian Zero Crossing Detector yang tidak pakai program arduimo ada ngak Pak ? Zero Crossing detector tsb untuk tambahan Syncronize Zero Crossing pada ATS biasa yang terdiri 2 kontaktor AC, Relay AC dan DC dan Timer TDR ? 🙏
1. when the AC voltage passes 0V either when from negative to positive or vice versa. 2. serves to determine the occurrence of a change of polarity, which means the state of the phase angle is 0 deg or 180 deg. 3. This video and the previous video show how to use it. 4. on devices that require phase angle information, such as frequency counter, phase comparison, synchronization and so on. I hope it helps, if there's something I'm missing, don't hesitate to ask again
bro can you please me help with your inverter SPWM code, I want to reduce switching frequency from 10khz to 5khz and keeping base frequency 50hz. Efficiency is good , it just has more heating, and reducing switching freq. will help. I've tried changing it myself , but there is few pulses here and there, which are messing with output wave.
since you need 5kHz intstead 10kHz, you need to do are: 1. change ICR1 value (on setup) from 800 to 1600. 2. edit the look up table value from 100 entries to 50 entries (use LUT entries 0,2,4... etc and delete entries 1,3,5... etc) so you have LookUp1[] = 0,50,100... etc. then multiply by 2 so LookUp1[] = 0, 100,200... etc. 3. in ISR change if (num >= 99) { // = 100) { // toggle left bridge (50Hz) !!! from 100 to 50. i think thats all
@@yopiediy i did all of that but then arduino pin D11, D12 ( which goes high for full phase using PORTB ie.10ms) does not match properly with pwm pulses. Causing spike in output wave when it changes phase
Suara mas yopie mengingatkan saya pada pembaca berita "dunia dalam berita" jaman saya SD😀, sukses selalu mas.

bner2 matkul elka analog digunain disini ya, pdhal saya g nyangka rangkaian ZCD bisa sbgitu kompleks dan berguna skli. terima kasih pak
Sami sami
Thanks for sharing, I love watching your tutorials and it helps me to understand Arduino/ atmega328 better and how to use them
بارك الله فيك
Baru up lg om 😊
hehe agak sibuk di dunia nyata😴
Muchas gracias por compartir tan interesantes proyectos
de nada, gracias por mirar
Alhamdulillah nongol lagi, semoga sehat selalu kang.
alhamdulillah, aamiin
Can y make the complete inverter with raspberry pi pico. .❤️
I've tried on RPI pico and it works fine, you need to adjust the coding of arduino nano to rpi pico.
master arduino... , request MPPT solar carge controler , with EEPROM to costum setting, with pushbutton .. sangat aq tunggu mas karna pingin buat projek ini , trimakasih
blum sempet experiment lagi, nanti klo udah bakalan sy upload
Siap mas, di tunggu..

🙏
Ada, dipasaran namanya synchroscope
@@yopiediy ada yang pakai hvd, ngak tau bagaimana hvd bisa sbg detector sudut phase 0⁰
Please I want more understanding about zero cross
1. It's meaning
2. It's functions
3. How to use it and
4. Where and when to use it
Thanks

When new video come ?
#3 soon, please wait
Can you make MPPT chage
maybe someday, I haven't studied it yet🙏

@@him7748 also try change delayMicroseconds(60) in ISR section to lower value.
Bro do you work as a freelancer too?
I need somehelp with your code of sine wave inverter.
