7.1.7 sca_eln::sca_c

The class sca_eln::sca_c shall implement a primitive module for the ELN MoC that represents a capacitor.

The primitive shall contribute the following equationEquation (7.2) to the equation system:

(7.2) ip,n(t)=d(value*vp,n(t)+q0)/dt

where value is the capacitance in farad, q0 is the initial charge in coulomb, vp,n(t) is the voltage across the capacitor between terminals p and n, and ip,n(t) is the current through the capacitor flowing from terminal p to terminal n.

If the initial charge q0 is set to sca_util::SCA_UNDEFINED, the primitive shall contribute no equation to the equation system for the first calculation. In this case, the initial charge q0 shall be calculated as follows:

q0 = value ? vp,n0, where vp,n0 is the voltage across the capacitor after the first calculation.

The element supports current tracing. The current is flowing from terminal p to n through the capacitor.
