Voltage source

Block appearance in REPEAT VISION

 The Voltage source block ensures operation of non-ideal sourceof direct or sinusoidal voltage.

 The voltage between the inputand output ports is determined by the following expressions:

• DC source type (1) :

(1)\[ U=E-\mathrm{I}\mathrm{r} \]

where:

 \(E\) - DC voltage set point;

 \(I\) - voltage source current.

• AC source type (2) :

(2)\[ U=U_{m}\mathrm{s}\mathrm{i}\mathrm{n}\left(2\pi \mathrm{f}\mathrm{t}+\phi \right)-\mathrm{I}\mathrm{r} \]

where:

 \(U_m\) - amplitude value of voltage, [V];

 \(f\) - source frequency, [Hz];

 \(\phi\) - initial phase, °;

 \(r\) - internal resistance, [Ohm].
