The thermal simulation circuit creates a thermal simulation model (ROM*1) of the device losses calculated in the electrical simulation and a typical PTC heater (including a water-cooled environment), and calculates the temperature of the IGBTs and shunt resistor.

In electric vehicles that do not produce engine waste heat, by using a PTC heater as a heating heat source and quickly bringing the temperature to the appropriate temperature, it is possible to instantly improve driving stability and cabin comfort. It is also used as a safe discharge circuit for high voltage batteries.

The PTC (Positive Temperature Coefficient) heater plate, part ID: PTC, is a ceramic-based heating element designed to provide efficient and safe heating. Unlike traditional heating elements, the PTC heater plate is self-regulating, meaning it automatically adjusts its resistance to maintain a constant temperature.

Regardless of the power topology used in the PTC heater module design, an input filter circuit may be needed to feed into the rest of the power supply in order to help it meet EMI requirements.

Positive Temperature Coefficient (PTC) heaters are self-regulating heaters that run open loop without any external diagnostic controls. While traditional fixed-resistance heaters employ wires and coils to generate heat, PTC heaters use conductive inks printed on thin, flexible polymer-based substrates.

A PCB substrate for a high frequency PWM circuit for PTC heater control for a vehicle is divided into a high voltage inlet where a circuit component of a high voltage PWM ground is mounted...

EPCOS offers a wide selection of PTC thermistors for overcurrent protection covering rated volt-ages up to 1000 V (with rated current 8 mA) and rated currents up to 2.1 A (rated voltage 12 V).

This temperature sensing circuit uses a resistor in series with a positive–temperature–coefficient (PTC) thermistor to form a voltage–divider, which has the effect of producing an output voltage that is linear over temperature.
