:: Power Electronics ::

Ha. Ape kejadahnye Power Electronics dijadikan tajuk post kali ni?? Guess what? Tade. Saje nak share, ape yg dipelajari. Sebenarnye Power Electronics (or singkatannye PE) ni adelah salah satu subjek yang ana amik semester ni. Subjek yang 3 credit hours ni meletakkan Analogue Electronics II sebagai subjek pre-requisitenye.

Lecturer yang mengajar ana subjek ini bernama Ms. Khairunnisa’ Md Hasan. Merupakan bekas graduan kampus ana sendiri. Textbook yang digunekan:

PE

OK. Apekah tugas PE nih? Basically, main tugas of PE ni adelah untuk control dan convert electrical power from one form to another. Form mende lak ni? OK. Ade 2 jenis electrical power yg boleh dikatekan semua orang tau. DC (Direct Current), dan AC (Alternating Current). Therefore: Conversion yang ade ialah:

  • AC to DC conversion (the converter is known as rectifier)
  • DC to AC conversion (the converter is known as inverter)
  • DC to DC conversion (the converter is known as chopper)
  • AC to AC conversion (the converter is known as cycloconverter/ac voltage controller)

Sume converters ni adelah based on semiconductor power switches (of course made by power semiconductor devices). Apekah power semiconductor devices yang ade? Banyak. Tapi boleh dikelaskan kpd 3 groups:

  1. Diodes
  2. Thyristors
  3. Controllable switches

To be continued, insyaAllah.
