Description

../../_images/cth.svg../../_images/cth_ansi.svg

This component provides an ideal thermal capacitance between its two thermal ports or between the thermal port and the thermal reference. See section Configuring PLECS for information on how to change the graphical representation of thermal capacitors.

Parameters

Capacitance

The value of the capacitor, in \((\mathrm{J/K})\). All finite positive and negative values are accepted, including 0. The default is 1.

Initial temperature

The initial temperature difference between the thermal ports or between the thermal port and thermal reference at simulation start, in degrees Celsius \((^\circ\mathrm{C})\). If left blank or if the value is nan, PLECS will initialize the value based on a thermal DC analysis, see Temperature Initialization.

Probe Signals

Temperature

The temperature difference measured across the capacitance, in degrees Celsius \((^\circ\mathrm{C})\). A positive value is measured when the temperature at the terminal marked with “+” is greater than the temperature at the unmarked terminal.
