Power Electronics, AC-DC Machines and Electrical Drives Simulation Software

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.
