Simulators simplifies e-train design

A new version of the Spice analogue simulator called Qspice can simplify the development of motor control for EV powertrains and other vehicle motors (writes Nick Flaherty). The Qspice simulator has been written by Mike Englehardt, the creator of several versions of the Spice analogue simulator. It can integrate digital elements such as controllers with no performance penalties alongside the analogue power device simulation.
