Rectifiers and Inverters
Extends from Base.Icons.Library (Package icon 'Library').
Information
The package contains passive rectifiers and switched/modulated inverters. Different implementations use:
- Phase-modules (pairs of diodes or pairs of IGBT's with antiparallel diodes).
- The switch-equation for ideal components.
- The time-averaged switch-equation. As models based on single-switching are generally slow in simulation, alternative 'averaged' models are useful in cases, where details of current and voltage signals can be ignored.
Thermal losses are proportional to the forward voltage drop V, which may depend on temperature.
The temperature dependence is given by
V(T) = Vf*(1 + cT[1]*(T - T0) + cT[2]*(T - T0)^2 + ...)where Vf denotes the parameter value. With input cT empty, no temperature dependence of losses is calculated.
The switching losses are approximated by
h = Hsw_nom*v*i/(V_nom*I_nom) use: S_nom = V_nom*I_nomwhere Hsw_nom denotes the dissipated heat per switching operation at nominal voltage and current, averaged over 'on' and 'off'. The same temperature dependence is assumed as for Vf. A generalisation to powers of i and v is straightforward.
NOTE: actually the switching losses are only implemented for time-averaged components!
