Gambaran Keseluruhan Thyristor Kawalan Fasa

Tiristor kawalan fasa, sering dirujuk sebagai triac atau SCR (Penerus Terkawal Silikon) dalam aplikasi tertentu, ialah peranti semikonduktor yang digunakan untuk mengawal jumlah kuasa yang dihantar kepada beban dengan melaraskan sudut fasa di mana bentuk gelombang AC dibenarkan untuk mengalir. Kaedah kawalan ini dikenali sebagai kawalan sudut fasa atau ringkasnya kawalan fasa. Tiristor kawalan fasa digunakan secara meluas dalam pelbagai aplikasi yang memerlukan pengawalan kuasa elektrik yang tepat, seperti dimmer pencahayaan, kawalan kelajuan motor, pengawal suhu, dan banyak lagi.

Ciri-ciri Thyristor Kawalan Fasa

Kawalan Sudut Fasa: Membenarkan pelarasan titik pengaliran dalam setiap separuh kitaran bentuk gelombang AC, membolehkan kawalan tepat ke atas purata kuasa yang dihantar ke beban.

Kecekapan Tinggi: Beroperasi dengan kerugian yang minimum semasa menjalankan, menyediakan kawalan kuasa yang cekap.

Kekonduksian Dwi Arah (Triak): Untuk aplikasi AC, triac boleh mengalirkan arus dalam kedua-dua arah, menjadikannya sesuai untuk kawalan gelombang penuh beban AC.

Kekonduksian Sehala (SCR): SCR mengalirkan arus dalam satu arah sahaja dan biasanya digunakan untuk kawalan separuh gelombang beban AC atau DC.

Pencetusan Gerbang: Pengaliran bermula apabila arus kecil dikenakan pada terminal get, membolehkan kawalan mudah pada titik hidup.

Arus Selak: Setelah dicetuskan, thyristor terus mengalir sehingga arus yang melaluinya jatuh di bawah paras tertentu yang dipanggil arus pegangan.

Sensitiviti Suhu: Prestasi boleh dipengaruhi oleh perubahan suhu, memerlukan pertimbangan pengurusan haba dalam reka bentuk.

Penilaian Voltan dan Arus: Tersedia dalam julat luas penarafan voltan dan arus untuk memenuhi keperluan aplikasi yang berbeza.

Penjanaan Bunyi: Boleh menjana gangguan elektromagnet (EMI), memerlukan penapisan dan perisai yang betul dalam aplikasi sensitif.

Mekanisme Perlindungan: Selalunya termasuk perlindungan terbina dalam terhadap voltan lampau dan keadaan arus lebih untuk melindungi peranti dan sistem yang disambungkan.
