CASPOC is a powerful, innovative system simulator designed for the simulation of Power Electronics and Electrical Drives. Using CASPOC, modeling power electronics, electrical machines, load and control in one multilevel model is fast and simple. This multilevel model includes a circuit level for the modeling of switched mode power supplies, a component level for the modeling of electrical machines/loads and a system level for the modeling of control algorithms.

Only CASPOC combines the ease of use of visual drag and drop schematic development, the productivity of modeling language, the power to view simulation results in ‘real time’ during the simulation in auto-scaling windows, and the world’s fastest simulation performance with no convergence problems.

LORENTZ-HF also calculates near and far field results, power and directive gain, radar cross-section, axial ratio, and input impedance, admittance and scattering parameters.

CASPOC is used in the design and simulation of complex power and control devices and systems such as: Rectifiers, DC Converters, AC Converters, Resonant Converters, Power Engineering, Induction Machines, Vector Controls, Mechanics, Active Filters, Harmonics, DC Machines, Stepper Motors and more, used in industries such as Aerospace, Automotive, Utility, Industrial, Transportation and Commercial Electronics.

  • Notes and figures can be added to the schematic
  • Ability to create scripts to run CASPOC in batch mode
  • Parameter sweep for any component parameter
  • Bode diagram for any system to identify stability, impedance and audio susceptibility. Gain/phase margin, bandwidth for any type of power electronics – no averaging models are required
  • Project management data can be stored with the simulation project
  • Archive the entire project with one click
  • Many samples on power electronics, electrical drives and sustainable energy are already pre-programmed

CASPOC Versions

The CASPOC Standard version is the most basic, yet fully functional version of CASPOC. The CASPOC Professional version includes extended features.


Try the CASPOC  FreeWare version. Although limited in nodes, you can run the samples and create your own models and simulate them!


Any sample can be viewed/simulated/animated in the Viewer. If there is no license, you can run a simulation and view the results. Certain parameters can be changed, indicated by the interactive components like the UPDOWN, KEY and ONOFF.

  • No license is required
  • View simulation results
  • No limitation on nodes and components in the Viewer
  • All samples from the tutorials. sample packages and the educational workbooks can be simulated/animated

Standard version
