Quasi real time simulation of power electronic systems

A software-driven quasi-real-time simulator is presented for power electronic circuits and systems. The use of multiple digital signal processors (DSPs) allows simulations at near-real-time speeds for a wide variety of complex power electronic systems. Digital and analog interfaces with the outside world allow monitoring of the variables while the program is being executed. This interactive feature is especially helpful in complex simulations and in realizing a testbed for actual power electronic controllers. The use of parallel DSPs allows extremely high computation speed, and the use of a bus-based broadcasting technique trims communication overhead to insignificant levels.<>
