The power behind the drive

An unusual piece of software that hails from Holland can be used to simulate power electronics and drive systems.

Caspoc was developed by Simulation Research, an engineering consultancy specialising in high-quality software for the power electronics and drives industries. The engineer can use the package to model a power electronics circuit, analog or digital control, electrical machines and behavioural equations of drive systems, components or other devices.

Modelling is based on a Spice-like netlist, a block diagram and the modelling languages Pascal or C. The software can combine the power converter, machine and control in one simulation, and using harmonic analysis, the engineer can compare harmonics with the IEC 555-2 limit or other norms.

Interactive buttons on the screen allow the designer to adjust parameters interactively during simulation. A maximum of nine circuit nodes define the power conversion circuit and a maximum of 14 system blocks define a mechanical load or a control.

The software is not expensive, runs on a PC and is gaining an international reputation because of the speed at which it reaches solutions. A cutdown, or `student’ version is also available which, although it contains the same functionality as the full version, does not include the modelling language.
