Isistimu yokwelapha i-corona ngokuyinhloko iqukethe i-generator,{0}}i-voltage transformer ephezulu, kanye nomshini wokwelapha. Ijeneretha inikeza amandla, kuyilapho{2}}i-voltage transformer ephezulu iguqulela i-alternating current (AC) ibe amandla kagesi aphezulu afanele ukwelashwa. Umnyombo womshini wokwelapha uyi-capacitor. Izinto okufanele ziphathwe zibekwe phakathi kwama-electrode amabili. Njengoba i-voltage ikhula kancane kancane, kwenzeka into ye-corona, edala i-oxidation ebusweni futhi iphule izibopho zamakhemikhali. Le nqubo ikhiqiza amaqembu e-hydroxyl, amaqembu e-carbon, namabhondi e-peroxide, okwenza ifilimu ibe rough futhi kusize ukunciphisa ukungcoliswa kwendawo.
Ngesikhathi sokwelashwa kwe-corona, ifilimu ivamise ukubekwa phakathi kwamarola amabili bese iphathwa nge-bipolar, ama-electrode agcinwe ebangeni elingamasentimitha ambalwa. Ukusebenza kokwelashwa kwe-corona kuthinteka isikhathi sokwelashwa, izinga lokushisa, nomswakama. Njengoba isikhathi sokwelashwa sincipha, amazinga okushisa akhuphukayo nokushintsha komswakamo kungase kuthinte amandla angaphezulu kwefilimu nokuthambisa. Ukuqinisekisa ukugoqa kwefilimu okubushelelezi, inqubo yokwelashwa kwe-corona kufanele igweme ukwakheka kwezigaxa kanye nokwanda kwamandla angaphezulu.
Ukwelashwa kwe-Corona kusetshenziswa kakhulu ezinhlotsheni zamafilimu ahlukahlukene, ikakhulukazi i-polypropylene namapulasitiki-aphansi-anamandla aphansi. Uma igebe lomoya lisethelwe ku-5 mm futhi i-voltage ilungiswa ku-560 kHz, ukukhishwa kwe-corona kungalawulwa ngokuphumelelayo ukuze kuqinisekiswe umphumela wokwelapha ongcono kakhulu.
