For homogeneous current and energy distribution it is recommended to combine only PTCEL of the same size and matched resistance value. Energy absorption per PTC in a network depends on current distribution in the network and as such on the individual PTC resistance value. PTCEL thermistors might be used in a series connection to further lower the inrush current, but not to increase the maximum allowed voltage levels. Following formula may be used to calculate the minimum number of PTCEL thermistors of the same size and matched resistance value that are required in a DC link or other capacitor bank application to properly charge or discharge a given amount of non-repetitive energy without follow current. The formula is valid for one charge or discharge operation within cool down period of at least 5 times the thermal time constant and for which the TPTC equals the Tamb before a consecutive operation. K x C x V[2] N ≥ --------------------------------------------------------------2 x Cth x (Tsw - Tamb) **Notes** - N is the number of PTCEL required in the network - C is the total capacitor value to charge or discharge in F - V is the maximum DC voltage on the capacitor C - Cth is the thermal capacity of one PTC in [J/K] (see table) - Tsw is the minimum switching temperature of the PTCEL (130 °C) - Tamb is the maximum ambient temperature at which the PTC needs to operate - K is the factor that determines the charging operation mode K = 1 for DC charging or discharging K = 0.96 for 3-phase rectified charging - K = 0.76 for single phase rectified charging ## **RESISTANCE VS.

## **Notes** - The minimum PTC resistance values under (pulsed) voltage are depending on actual minimum resistance value in the temperature range of 70 °C to 100 °C. The actual voltage dependency effect or R(Vp)/R(LV) ratio of ceramic PTC is depending on its resistance values at low voltage (R(LV)). The different curves represent the influence of (pulsed) voltage related to the PTCEL value types in the minimum resistance temperature range of 70 °C to 100 °C. A PTC resistance value R(LV) can be taken from the “Resistance vs Temperature” graphs and multiplied by a corresponding ratio to estimate the (minimum) resistance value and determine a maximum peak current at a defined voltage. Example: a PTCEL17R501TBE type has a Rmin. (see Electrical Data table) of 260 Ω at around 90 °C, and at a 1000 V peak-voltage the resistance will drop to 260 Ω x 0.43 (red curve) = 112 Ω, which will give rise to a peak-current of around 9 Ap. Actual peak currents that could be reached at certain voltage levels can be more precisely evaluated by using the available SPICE models - Also check the graph “Resistance vs. Temperature Pulsed” to see the typical resistance to voltage dependency effect on a PTCEL17R501TBE ## **RESIDUAL CURRENT VS.
