Ubushuhe bwa PTC ni umushyitsi wagenewe imodoka nshya zingufu.Ubushyuhe bwa PTC bushyushya ibinyabiziga byose, butanga ubushyuhe kuri cockpit yimodoka nshya yingufu kandi bujuje ibisabwa kugirango habeho defrosting na defogge.Ubushyuhe bwa PTC burashobora kandi gushyushya ubundi buryo bwikinyabiziga gisaba kugenzura ubushyuhe (urugero nka bateri).Ubushuhe bwa PTC bukora mugushushya amashanyarazi antifreeze kugirango ashyushye imbere hamwe nubushyuhe bwumwuka.Ubushuhe bwa PTC bushyirwa muri sisitemu yo gukwirakwiza amazi akonje aho ubushyuhe bwumwuka ushyushye bworoshye kandi bugenzurwa.Ubushyuhe bwa PTC butwara IGBTs hamwe namabwiriza ya PWM kugirango agenzure ingufu kandi afite ibikorwa byo kubika ubushyuhe bwigihe gito.Ubushuhe bwa PTC butangiza ibidukikije kandi bukoresha ingufu, bujyanye no kubungabunga ibidukikije muri iki gihe.
