PLECS Standalone Packages
Explore Autonomous Power Simulation with PLECS Standalone
If you require a simulation tool that functions independently from other tools, PLECS Standalone is a complete solution. This is a standalone tool for power electronic systems time–domain simulations, and provides a comprehensive framework to model more complex electrical circuits and control systems strategies independently from other platforms.
Faster, More Efficient Simulation Engine
When compared to PLECS Blockset, PLECS Standalone is much quicker due to a more advanced simulation engine. PLECS Standalone includes a powerful library of blocks, and is an excellent and inexpensive tool for falling quicker. The tool appropriately matches its use, and affords dynamic system simulations in both industry and academia.
Advanced Solvers for Different System Types
PLECS Standalone provides its own solvers to properly implement circuit equations. You can select between fixed-step or variable-step solvers, depending on your physical situation. If your system is designed with dynamic change, then one of PLECS Standalone‘s variable time-step solvers—either implicit or explicit—can achieve efficient and accurate simulations for both stiff and non-stiff models.
Smooth Simulations of Sampled Data Systems
Whether your sampled data systems are periodic, variable, or mixed in their sampling rates, PLECS Standalone can effectively model the procedures. Completing the model includes smooth operation of discrete and continuous optimization.

PLECS Blockset
PLECS Blockset is a dedicated toolbox for rapid and efficient simulation of power electronics systems in the Simulink environment. PLECS Circuit Blocks provide access to PLECS electrical circuit models and allow for connections to Simulink control algorithms for unified system simulation.
Integrated PLECS Circuit Blocks
In the Simulink model, each electrical circuit created in PLECS is represented as a single PLECS Circuit Block. PLECS Circuit Blocks can accept input signals to control electrical sources or switching devices and provide outputs through ports for measurement data, such as visualizing the data with scopes or analyzing the data in MATLAB or feedback control loops.
Users have complete access to Simulink‘s libraries and extensions, allowing for the development of sophisticated control strategies and seamless integration of multi-domain systems.
Easy–to–Use Schematic Editor
If you have experience in Simulink, then moving to the PLECS schematic editor is very easy. If you double–click a Circuit Block, you will open the editor and be able to drag and drop to create and connect components. The basic design of the interface is intuitive; you can add input/outputs to the schematic to specify how the system is to interact.
Native Use of Simulink Solvers
During simulation, PLECS automatically converts circuit designs into a set of equivalent mathematical equations. These equations are then solved directly by the Simulink engine, eliminating the need for co-simulation. The PLECS Blockset supports both fixed-step and variable-step solvers, ensuring high compatibility with Simulink’s simulation configurations.

RT Box – Advanced HIL Simulator for Power Electronics
RT Box is a high-performance HIL simulator for power electronics applications, designed to deliver precise, real-time testing for control systems. With its advanced features and integration with the PLECS simulation platform, RT Box provides engineers with a reliable solution for both Hardware-in-the-Loop (HIL) simulation and Rapid Control Prototyping (RCP).
Hardware-in-the-Loop (HIL) Simulation for Power Electronics
HIL simulation using RT Box allows seamless interaction between real controllers and simulated power circuits. This enables developers to safely test control strategies under both typical and fault conditions, without risking damage to physical hardware.
Real-time simulation is particularly challenging in power electronics due to rapid switching and short time constants. The RT Box overcomes these challenges with cutting-edge features like:
- Sub-cycle averaging for accurate PWM interpretation
- Nanostep technology for ultra-fast processing
- Nanosecond-resolution sampling of PWM signals
These technologies enable simulations at switching frequencies of several hundred kHz with minimal latency, offering exceptional fidelity in your HIL simulator setup.
Rapid Control Prototyping (RCP)
When the final controller hardware is unavailable, RT Box steps in as a temporary controller. It can:
- Generate complex PWM signals
- Read sensor data through analog inputs
- Interface with encoders and resolvers for motor control
- Communicate using SPI, CAN, and other protocols
This capability is especially valuable in R&D environments, where testing the power stage must proceed before hardware finalization.
Parallel Computing with CPU and FPGA
At its core, the RT Box HIL simulator features a Xilinx Zynq chip, combining multiple CPU cores and an FPGA. This hybrid architecture enables:
- Flexible model partitioning
