Zusammenfassung:The invention relates to a method (7) for determining an output temperature (TOUT) of a fluid after flowing through a PTC heater (1) with a PTC heating element (2).In the method:- a current (I) of the PTC heating element (2), a supply voltage (U) of the PTC heating element (2) and a duty cycle (PWM) of the supply voltage (U) are determined, and- the output temperature (TOUT) of the fluid is calculated based on the current (I), the supply voltage (U) and the duty cycle (PWM).The invention also relates to a PTC heater (1) for carrying out the method (7).
