Features of CASPOC, A Simulation Experience!

CASPOC is best suited for modeling and simulating physical systems. It enables full-system virtual prototyping of applications in analog/power electronics, electric power generation/conversion/distribution and mechatronics.

CASPOC is especially designed for systems simulation. Real world electromechanical problems require the ability to design magnetic and electric components that produce needed forces and torques, such as motor and solenoid design. Optimal electromechanical designs are restricted by package size, weight, thermal considerations, available power and many other environmental limitations.

By using CASPOC, engineers can model, load and control in one multilevel model. This multilevel program 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. For educational purposes, CASPOC is the only simulator in the market with a circuit animation feature, which contains a "Freeze and Go Back" function.

By combining a variety of technologies into one single user interface, CASPOC combines the power and versatility required to challenge sophisticated design problems.

Efficient design and analysis tools

In addition to the modeling environment and the component library is available in Caspoc several tools that simplify the design and analysis of power electronic systems .

  • During and after the simulation results are visualized with the Caspoc Scope . The Caspoc Scope is similar to a real oscilloscope , as it is used in electronics development . It allows the user to accurately represent relevant curves and to use the data for post-processing and reporting.
  • With the built-in analysis tools can be determined in a simple way the steady-state operating condition as well as the transfer functions of open and closed loop . In addition, the state-space matrices of the system for further analysis can be read .
  • With the help of simulation script the user can change parameters and run automated simulations and analyze simulation results and rework .
  • The separately available Caspoc Coder allows the generation of C code for a modeled in Caspoc Blockset circuit .
