Trapezoid Voltage

Trapezoidal voltage source

Modelica Standard Library

	Description
	The Trapezoid Voltage source generates a periodic trapezoidal waveform.

	Equations
	$i = i_{p} = - i_{n}$ $v = v_{p} - v_{n} = V_{0} + V_{h} {\begin{array}{c} 0 & t' < 0 \\ \frac{t'}{T_{r}} & 0 \leq t' < T_{r} \\ 1 & T_{r} \leq t' < T_{r} + T_{w} \\ \frac{T_{r} + T_{w} + T_{f} - t'}{T_{f}} & T_{r} + T_{w} \leq t' < T_{r} + T_{w} + T_{f} \\ 0 & otherwise \end{array}$ $t' = t - T_{0} - k T, k = \{0, 1, \dots, n - 1\}$
