Nā hemahema a me nā pilikia o ka dimming SCR
Eia nō naʻe, aia kekahi mau pilikia me ka dimming SCR.
1. Hoʻopau ʻo Thyristor i ka nalu o ka hawewe sine, a laila e hōʻemi ana i ka waiwai o ka mana, ʻoi aku ka liʻiliʻi o ka PF ma mua o 0.5, a ʻo ka liʻiliʻi o ke kihi conduction, ʻoi aku ka ʻino o ka mana (0.25 wale nō ma 1/4 kukui).
2. Pēlā nō, hoʻonui ka hawewe non-sinusoidal i ka coefficient harmonic.
3. Hiki i nā nalu non-sinusoidal ke hana i nā hōʻailona interference koʻikoʻi (EMI) ma ka laina
4. He mea maʻalahi ka paʻa ʻole i ka haʻahaʻa haʻahaʻa, no laila pono e hoʻohui ʻia kahi pale bleeder. Pono e hoʻopau kēia mea pale wai ma kahi o 1-2 watts o ka mana.
5. ʻO nā pilikia i manaʻo ʻole ʻia e hiki mai i ka wā e hoʻopuka ai ka thyristor dimming circuit maʻamau i ka mana hoʻokele o ka LED, ʻo ia hoʻi, ʻo ka kānana LC ma ka hoʻokomo e hoʻoulu i ka thyristor e oscillate, ʻaʻole ia he mea nui no ke kukui incandescent. ʻAʻole ʻike ka maka o ke kanaka i kēia oscillation. Akā no ka mana hoʻokele LED, hoʻokumu ʻia ka leo leo a me ka flicker.
