 As seen in the Schematic, for our discharge circuitry a PTC (PTCEL13R251NxE) is used. The total capacitance of the DC-link capacitor from the two inverters that we are using is \SI{200}{\micro\farad}, and the maximum voltage of the accumulator is 403.2V. Using the RC discharging circuit equation, we obtain the highest resistance that the PTC can have so that we are still within the 5s discharge limit.

 Therefore, the total amount of discharge we can carry out before the time exceeds \SI{5}{\second} is $\SI{174}{\joule} / \SI{16.26}{\joule} = 10.7$ --- ten times.
 
+\section*{Permanent TS Voltage}
+We can find the equilibrium temperature by finding the temperature at which the heat loss is equal to the power emitted. Using the model for LTSpice from Vishay, we can see what the heat loss is at equilibrium. (fig. ) We can see that it is about \SI{2.56}{\watt} Since the dissipation factor is \SI{19.5}{\milli\watt/\kelvin}, we can calculate what the temperature difference $\Delta T$ is.
