PowerSensor

Measures the instantaneous electrical power flowing through or consumed by a circuit.

This component utilizes an internal VoltageSensor and an internal CurrentSensor to determine electrical power. The voltage is measured between pins pv (positive voltage) and nv (negative voltage). The current is measured as it flows from pin pc (positive current) to pin nc (negative current). The instantaneous power is calculated as the product of these two measurements:

\[P = V \cdot I\]

where V is the voltage measured by voltage_sensor.v and I is the current measured by current_sensor.i.

Usage

PowerSensor()

Connectors

  • pc - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
  • nc - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
  • pv - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
  • nv - This connector represents an electrical pin with voltage and current as the potential and flow variables, respectively. (Pin)
  • power - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{equation} \left[ \begin{array}{c} \mathtt{power}\left( t \right) = \mathtt{current\_sensor.i}\left( t \right) \mathtt{voltage\_sensor.v}\left( t \right) \\ \mathrm{connect}\left( pv, voltage_{sensor_{+}p} \right) \\ \mathrm{connect}\left( voltage_{sensor_{+}n}, nv \right) \\ \mathrm{connect}\left( pc, current_{sensor_{+}p} \right) \\ \mathrm{connect}\left( current_{sensor_{+}n}, nc \right) \\ \mathtt{voltage\_sensor.p.i}\left( t \right) = 0 \\ \mathtt{voltage\_sensor.n.i}\left( t \right) = 0 \\ \mathtt{voltage\_sensor.v}\left( t \right) = \mathtt{voltage\_sensor.p.v}\left( t \right) - \mathtt{voltage\_sensor.n.v}\left( t \right) \\ \mathtt{current\_sensor.p.v}\left( t \right) = \mathtt{current\_sensor.n.v}\left( t \right) \\ \mathtt{current\_sensor.p.i}\left( t \right) = \mathtt{current\_sensor.i}\left( t \right) \\ \mathtt{current\_sensor.n.i}\left( t \right) = - \mathtt{current\_sensor.i}\left( t \right) \\ \end{array} \right] \end{equation} \]
