Zotenthetsera za PTCamagwiritsidwa ntchito m'magalimoto atsopano amphamvu ndipo amatha kupereka makina otenthetsera ogwira ntchito bwino komanso otetezeka. PTC imapereka mphamvu ndi magetsi kuchokera ku batire yamagetsi amphamvu ya magalimoto atsopano amphamvu, ndipo imayang'anira chinthu chotenthetsera chomwe chiyenera kuyatsidwa ndi kuzimitsidwa kudzera mu IGBT kapena zida zina zamagetsi. MCU imazindikira kuwongolera kwa makina a PTC posonkhanitsa zambiri zamagetsi ndi magetsi, ndipo imagwiritsa ntchito ma transceivers kuti ilumikizane ndi ma module ena.
Chotenthetsera choziziritsira cha PTC, yotchedwansoChotenthetsera cha PTC, imapangidwa ndi PTC ceramic heating element ndi aluminiyamu chubu. Mtundu uwu wa PTC heater uli ndi ubwino wa kukana kutentha pang'ono komanso kugwiritsa ntchito bwino kutentha kwambiri. Ndi kutentha kokhazikika komanso kusunga mphamvu zokhachotenthetsera chamagetsi. Thermistor ya PTC yotenthetsera kutentha kosasintha imakhala ndi mawonekedwe otenthetsera kutentha kosasintha. Mfundo yake ndi yakuti pambuyo poti PTC thermistor yayatsidwa, imadzitenthetsera yokha ndipo mphamvu yokana imalowa m'dera losinthira. Kutentha kwa pamwamba pa PTC thermistor yotenthetsera kutentha kosasintha kudzakhalabe ndi phindu losasintha. Kutentha kumeneku kumangogwirizana ndi PTC. Kutentha kwa Curie kwa thermistor kumagwirizana ndi mphamvu yogwiritsidwa ntchito ndipo kwenikweni sikukhudzana ndi kutentha kwamlengalenga.
Pali mitundu yambiri ya ma heater a PTC, ndipo amagawidwa m'njira zosiyanasiyana. Malinga ndi kapangidwe kake, ma heater a PTC amagawidwa m'ma heater a PTC okhazikika okha, ma heater a PTC othandiza,Zotenthetsera mpweya za PTC, ndi zina zotero; malinga ndi njira zosiyanasiyana zoyendetsera magetsi, ma heater a PTC akhoza kugawidwa m'magulu awiriZotenthetsera madzi za PTC, Zotenthetsera mpweya za PTC, zotenthetsera za infrared radiation, ndi zina zotero. Pakati pawo,zotenthetsera mpweya za PTCamagwiritsidwa ntchito kwambiri m'magalimoto amagetsi.
