Guideline FYP1 Presentation
Guideline for FYP 1 Presentation
In brief, the presentation should direct the panel/audience to what you plan to do for FYP2. The outline of the presentation should have at least:
- Introduction / title background (1-2 slide)
A brief introduction to the topic. Why is Multilevel inverter better than conventional inverter? (1-2 slides). Briefly explain the advantages of THD voltage output value, filter output design.
- Literature Review (8 slides)
Conduct a review on several conventional multilevel inverters; Cascaded, Neutral-point clamp, and Flying capacitor multilevel inverters. Their advantages and limitations.
Review on switching for the multilevel inverter. There are several types, i.e., fundamental frequency switching technique, i.e., selective harmonics elimination, near to dc level modulation (NLM). For PWM, we have a multi-carrier PWM technique.
- Problem Statement (1 slides)
The conventional MLI circuit has several limitations that can be overcome by new MLI circuits, such as high switches to produce a high output level. We are proposing a circuit that uses minimum switches but able to produce a high number of levels. Show the circuit is a must!
- Objectives (1 slide)
List down at least three objectives
- Scope of work (1 slide)
Show the panel the scope / the limit of the work. For example, the work only involves simulations and performance analysis based on the model developed in Matlab/Simulink. The switching technique use is the multi-carrier PWM technique. The performance analysis will cover output voltage spectrum analysis. THD analysis with different load profiles, etc.
- Methodology (4 slides)
Show the plan to achieve the objective. Show your Gant chart here.
- Preliminary Result (2 – 3 slides)
You should by now able to simulate cascaded multilevel inverter using multi-carrier PWM (I have share file). The result of this preliminary study will be used as a comparison study with your proposed MLI circuit.
Show the Cascade MLI. Show the parameters, i.e., Vdc, switching frequency, load value etc. (in a table). Show the PWM switching signal used to control the switches. Lastly, show the output voltage waveform and verified it with the harmonic spectrum.
- Conclusion ( 1 slide)
- Reference list (show only the major and cited in the presentation)

Desaru 2
Bertemu lagi..saya pamerkan landscape kedua dari Desaru. Minggu depan ke Desaru lagi..kali ni menginap di Lotus Seaview…agak jauh dari Desaru dan dah dekat dengan Pekan Rengit, Pengerang
Desaru sunrise
Salam
sudah agak lama saya tak pergi bercuti bersama keluarga besar sebelah isteris saya. Sepatutnya, bulan ini kami adakan Hari Keluarga di Kuantan. Tapi kerana penangan Covid-19 yang tidak juga reda, kami terpaksa tangguhkan.
Gambar ini dirakam pada 26 Disember 2020. Saya inap di Lotus Desaru resort, tapi di situ tiada objek atau subjke yang menarik. Dari jauh saya lihat deretan batu. Deret batu terletak dalam kawasan pantai Sand & Sandal Hotel (dulu dikenali sebagai Pulai Desaru). Jauh jugak lah berjalan kaki..tambah tambah lagi tanha pasir sangta lah lembut..memang semput kalau tak exercise.
Legoland Video
Masih dalam mood cuti..(hahahah)..Video hasil tak seberapa..buat pun dalam 1 hari je..banyak yang lari…tak larat nak refine..hentam sajalah

Legoland Malaysia
Bercuit di Legoland Malaysia. Masih dalam musim Covid-19..SOP seboleh bolehnya dijaga..kali kedua ke sini
Alhamdulillah
Alhamdulillah. Best Paper Award IEEE PECON 2020 under Power Electronics Track
Style of Post Processing
bergantung kepada sesautu gambar dan mood. Itu lah style of processing saya. Untuk gambar UTM ni, amat sukar untuk seimbangkan antara kawasan yang cerah iaitu langit dan kawasan foregound iaitu kawasan kampus UTM. Contrast terlalu tinggi. Drone pulak tak boleh nak pasang GND atau RGND ..(memang tak de pun hihih)..
Saya memang tak recommend pasang filter di depan lens drone sebb akan menyebabkan beban berlebihan pulak pada motor camera.
So untuk menyimbangkan kecerahan kedua dua kawasan, terpaksa buat luminance masking…. Ambil gambar yang sama berlainan exposure. Selalunya saya akan kekalkan ISO serendah yang mungkin iaitu ISO100. Aperture tak boleh control, so hanya control shutter speed…shutter speed tu pun agak agak je..Buat pakai manul mode..jangan pula pakai auto mode sbb selalunya ISO akan tinggi untuk compensate shutter speed yang slow. Banyak noise nanti..sia sia je…
So Luminance masking yang saya pakai ni adalah Raya Pro (kena beli ye)..kalau nak percuma pun ada, iaitu Easy Panel…saya rasa Easy Panel pun dah cukup dah
Masjid UTM..lagi
memang saya akan prgi ke satu satu tempat banyak kali untuk merakam..sebab setiap masa, kalau bernasib baik dapat merakam langit yang cantik
