Description
Block Capacitor simulates a linear capacitor described by the following equation:
where
-
— current;
-
— capacity;
-
— tension;
-
— the time.
The parameters of the series resistance and parallel conduction reflect small parasitic effects. Parallel conduction directly on the capacitor can be used to simulate dielectric losses or leakage current.
The series resistance can be used to simulate the series resistance of a capacitor or the resistance of contacts. Modeling of some circuits may require a small series resistance.
Ports + and − represent the positive and negative terminals of the capacitor, respectively. The capacitor current is considered positive if it flows from the positive terminal to the negative one, and the voltage across the capacitor is equal to the potential difference at the ports. .
Variables
Use the Initial Targets parameter group to set the priority and initial target values for the block parameter variables before modeling. For more information, see Configuring physical blocks using target values.
