电力电子系统模拟

PLECS产品是一套能在MATLAB和Simulink环境下快速模拟电力电子电路系统的工具。新版本的特色包括热模拟，并可透过PLECS Viewer与无PLECS License的使用者分享电路模型。

PLECS的功能包括热分析，其热函式库让使用者可将热设计纳入电力电路的电子设计中，使用者可定义与温度相关的热传导和每个半导体元件的开关损耗能量分布；也可收集由半导体和电阻器而损耗的能量，并使用热电阻和电容元件来模拟热的行为。

完整授权版本的PLECS，可以产生一种内含特殊认证的PLECS电路模型，使用者可以使用免费的PLECS Viewer来开啟这样的电路模型(但不能修改)，以达到分享电路模型的目的。该工具并扩增了三相变压器函式库包括three-leg和five-leg 配置的模型，含有core saturation以及variable phase shift angles。

此外PLECS 具备离散状态空间方法的模拟参数「Refine factor」可让使用者在模拟离散式电路模型时，Time-Step会比使用Simulink模型时要来的小。该工具并支援无刷直流机械、基纳二极体 (Zener Diode)、3D查表(Look-Up Table)等元件。

PLECS® Standalone is an autonomous software package for time-domain simulation of power electronic systems. If you want to be independent from other simulation platforms, PLECS Standalone gives you the all-in-one solution for modeling complex electrical circuits and sophisticated controls in a single environment.

Thanks to its optimized engine, PLECS Standalone runs much faster than the PLECS Blockset. With the comprehensive block library, PLECS Standalone offers a cost-effective yet powerful solution for dynamic system simulation in general.

Dedicated solvers

PLECS Standalone comes with an own engine for solving the circuit equations. The user can choose between variable-step and fixed-step solvers. Variable time-step solvers are generally preferred for accurate and efficient simulations, because they adopt the step size during the simulation depending on model dynamics. PLECS Standalone provides optimized implicit and explicit variable-step solvers for stiff and non-stiff systems.

Sampled data systems

The simulation engine allows to model sampled data systems, i.e. discrete systems that change only at distinct times. You can model systems that are sampled periodically or at variable intervals, systems that contain blocks with different sample rates, and systems that mix continuous and discrete blocks.

Interoperability

Simulation models can be exchanged with users of the PLECS Blockset using import and export functions. All library components from PLECS Standalone are also available in the library of the PLECS Blockset. When importing a model created with the PLECS Blockset, the Simulink® part is ignored.
