   Web-Based Simulation of Power Circuits for Design and Teaching
By £. Starzak; M. Zubert; B. Œwiercz; A. Napieralski [View]
[Download]

Abstract: Computer-aided simulation is essential in today’s power electronics. This implies the need for wellimplemented device models. Because of their specific structures, the power devices exhibit a different behaviour as compared to the low-power ones. Therefore, special device models are developed, ranging from purely behavioural to physical, the latter being most accurate. However, many popular circuit simulators still use only behavioural equivalent circuit models, making the recent advances in the modelling domain unavailable to a large number of users. In the paper, a free simulation package based on the Berkeley SPICE3f5 is presented [1]. The original simulator code has been modified as to include a modern physics-based PIN diode model. This proves that modern power device models may be supported by popular circuit simulation environments. In order to make the software along with the model widely available, a web-based user interface has been developed. Several features are emphasized that make the package particularly well-suited for educational purposes.

   Accuracy and Speed of Time Domain Network Solvers for Power Systems Electronics Applications
By M. Steurer; S. Woodruff; R. Wen; H. Lee; T. Baldwin [View]

Abstract: This paper investigates performance differences of fixed and variable time–step network simulation methods by comparing accuracy and execution time of five commercial packages. A set of benchmark cases covering multiple three-phase diode rectifiers and a PWM voltage source inverter show that fixed time–step methods are superior in terms of execution time for line-commutated circuits. However, even low switching frequency PWM applications may require very small time steps in order to lead to accurate results. It is concluded that PWM inverter control signals may be significantly in error even when wave forms appear correct when too large a time step is used.
