Current source and voltage source components
Introduction
There are two components of source type:
- the current source
- the voltage source
Current source: definition
A current source is an ideal current source defined by the function current- time I(t) that depends on the physical application, as presented in the table below.
| Application | Function I(t) | Description in Flux |
|---|---|---|
| Steady state AC |
predefined: I(t) = I0ej(ωt + φ) |
Rms value: (Ieff)=(1/ √ 2)I0 Phase: φ |
| Transient |
defined by the user: I(t) = … |
Formula: I(t) = … |
Voltage source: definition
A voltage source is an ideal voltage source defined by the function voltage - time U(t) that depends on the physical application, as presented in the table below.
| Application | Dependence U(t) | Description in Flux |
|---|---|---|
| Steady State AC |
predefined: U(t) = U0ej(ωt + φ) |
Rms value: (Ueff)=(1/√2)U0 Phase: φ |
| Transient |
defined by the user: U(t) = … |
Formula: U(t) = … |
Concerning formulas
The formula that sets the time dependence on the current or on the voltage in a transient application is a formula that comprises:
- constants and I/O (input/output) parameters
- functions (operators, usual mathematical functions, varying functions, …)
Example:
- I(t) = I0Sin(ω.t + φ)
- U(t) = U0Trapez(t, T1, T2, T3)
