Stop Losing Time to Slow, Inaccurate Power Electronics Simulations, Meet PLECS by Plexim

plecs-power-electronics-simulation-tool.webp

The industry's most trusted simulation platform for power electronics engineers is now smarter, faster, and more connected than ever.

Every power electronics engineer knows the pain: you set up a simulation, hit run, and then, you wait. Switching transients crawl, solver iterations pile up, and what should take minutes stretches into hours. By the time you spot an error, precious development time has already slipped away.

If this sounds familiar, you are not alone. Across R&D labs, universities, and product teams worldwide, slow and inaccurate power electronics simulation remains one of the most expensive bottlenecks in the design cycle. Deadlines slip. Costs balloon. Product launches get pushed.
But there is a better way and engineers across 60+ countries have already found it.

 

Meet PLECS (Piecewise Linear Electrical Circuit Simulation) by Plexim — the simulation for power electronics that changes everything.

The Real Cost of Traditional Power Electronics Simulation Tools

Before we talk about solutions, let us understand exactly why conventional circuit simulators struggle with power electronics.

Why Traditional Simulators Are Not Built for Power Electronics

Most general-purpose circuit simulators treat power semiconductors  IGBTs, MOSFETs, diodes, as highly non-linear elements. Every time a switch transitions between on and off states, the solver must recalculate a complex web of non-linear equations.

This creates several compounding problems for engineers:

 

  • Simulations slow dramatically during switching events, sometimes by 10x to 100x.
  • Numerical convergence errors force repeated solver restarts.
  • Small timesteps are mandatory near transitions, making long simulation runs impractical.
  • Model debugging becomes a time sink instead of a design task.
  • High-frequency switching applications — like GaN or SiC-based converters become nearly impossible to simulate efficiently

What Engineers Actually Need From a Power Electronics Simulator Tool

After speaking with hundreds of engineers, the requirements become clear:

 

  • Speed that keeps pace with iterative design.
  • Accuracy that holds up under hardware validation.
  • Seamless integration with control design workflows.
  • Reliable code generation that bridges simulation and production.
  • A platform the whole team can trust and standardise on

Introducing PLECS by Plexim: The Gold Standard in Power Electronics Simulation

PLECS  (Piecewise Linear Electrical Circuit Simulation) was purpose-built to solve exactly the challenges described above. Developed by Plexim, a Swiss company founded in 2001 with deep roots in power electronics research, PLECS takes a fundamentally different approach to how switching behaviour is modelled.

The Core Innovation: Piecewise Linear Modelling

PLECS models switches as ideal on/off elements with defined topological states, simplifying simulation. Key impacts include:

  • Each switching event requires only two integration steps.
  • The solver remains stable regardless of switching frequency.
  • Simulation speed vastly exceeds that of SPICE-based tools.
  • Long simulations, including thermal and steady-state analysis, can be conducted in real time.

Future Trends in Thermal Interface Materials: What's Next

Future trends in Thermal Interface Materials (TIM) are shaped by increasing power densities and the demand for compact, reliable electronics. Key trends for 2025 and beyond include:

  • Ultra-high conductivity fillers like boron nitride and graphene (10+ W/m·K)
  • Low-pressure dispensing materials for delicate wearables and medical devices.
  • Integration with two-phase liquid cooling for data center GPU clusters
    Self-healing silicone composites that repair micro-fractures.
  • Thinner bond lines with improved conductivity for next-gen SiC and GaN power devices.

PLECS Is Not Just a Speed Tool — It Is a Complete Design Platform

Speed alone would make PLECS worth considering. But the platform goes much further than that:

Why PLECS Is Trusted by Power Electronics Engineers Worldwide

PLECS is a power electronics simulation tool used globally across industries such as automotive, renewable energy, and aerospace. Trusted by leading companies and institutions, it excels in applications like EV powertrains, solar and wind inverter design, battery management, and aerospace power distribution.

 

Developed by Plexim, which has over 20 years of expertise, PLECS was created specifically for power electronics, enhancing simulation speed, accuracy, and usability. Engineers report significant benefits, including:

 

  • Reduced simulation times from hours to minutes
  • Faster design iteration cycles
  • Greater confidence in simulation results before prototyping
  • Smooth transition from simulation to production
  • A unified platform for team collaboration.

How PLECS Transforms Your Power Electronics Design Workflow

1. Design Smarter: Rapid Iteration From Concept to Validated Design

In the early stages of a power electronics project, engineering teams explore multiple topologies and control strategies. Every iteration that requires waiting hours for simulation results kills momentum and compresses the time available for optimisation.
With PLECS, engineers can simulate dozens of design variations in the time it would take a traditional tool to complete a single run. The piecewise linear approach keeps simulations fast even as circuit complexity grows, so teams can genuinely explore the design space rather than being forced into a single path by simulation constraints.

2. Simulate Faster: From Switching Transients to Thermal Analysis in One Environment

One of the biggest inefficiencies in traditional power electronics development is the fragmentation of the simulation workflow. Electrical simulation happens in one tool, thermal analysis in another, control design in yet another.
PLECS unifies all of these within a single simulation environment. Engineers can analyse switching transients, evaluate thermal behaviour of devices under load, and test control algorithm performance — all in the same model, without data handoffs or format conversions. This level of integration is a genuine competitive advantage in product development.

3. Deploy With Confidence: Auto-Generated, Production-Ready C Codet

The gap between simulation and production often leads to unexpected issues in projects, as control algorithms may not perform as intended due to coding errors. PLECS addresses this by providing automatic C code generation, allowing engineers to design and validate control algorithms in a simulation environment and then directly generate clean, documented embedded C code. This process reduces implementation errors and accelerates the transition from simulation to deployment.

4. Validate Safely: Hardware-in-the-Loop Testing Before You Build

PLECS supports real-time simulation and hardware-in-the-loop (HIL) testing, allowing teams to validate their designs against real control hardware before a single physical prototype is built. This capability is particularly valuable for high-power or safety-critical applications where prototype failures are expensive or dangerous.

PLECS Standalone vs. PLECS Blockset: Choosing the Right Configuration

PLECS Standalone
The standalone version of PLECS operates as an independent simulation environment with its own modelling framework, solver, and post-processing tools. It is ideal for teams that want a dedicated power electronics simulation tool without a dependency on MATLAB or Simulink. The standalone version offers the full suite of PLECS capabilities, including thermal modelling, code generation, and HIL integration.

PLECS Blockset for MATLAB/Simulink
The blockset version integrates PLECS directly into the Simulink environment, allowing engineers to use PLECS circuit models as blocks within their existing Simulink workflows. This configuration is particularly popular with teams that already have significant investment in Simulink-based control design, as it allows them to benefit from PLECS simulation speed while retaining their existing toolchain.
Both configurations share the same core simulation engine and component libraries, so simulation results are consistent regardless of which version your team uses.
