   Animation of Power Electronics and Electrical Drives
By P. J. van Duijsen; D. Lascu [View]
[Download]

Abstract: In this paper a new multilevel simulation/animation tool Caspoc®, [Simulation Research, 2001] is described, which during simulation animates the power electronic circuit. The user sees the level of the node-voltages, the level of the branch currents and most important, he can see the current path in the circuit. The simulation tool can animate any power electronic circuit or electrical drive. Examples of power electronic and electrical drive animations are given, which show the advantage of animation

   Modeling and Analysis of HF Interactions Between Cascaded Buck Convert
By J-C. Crebier; S. Busquets-Monge; R. Gannett; D. Boroyevich [View]
[Download]

Abstract: This paper deals with possible high frequency interactions between cascaded buck converters due to lack of switching pattern filtering. Based on time domain simulations and analytical approach, it is shown that if a HF disturbance signal is applied to the converter input voltage, the switching pattern operation may generate a modulation scheme that in turn leads to oscillations of the output voltage and the converter operating point. Analysis is provided in order to limit the impact of these interactions and to take advantage of the conclusions in applications such as distributed power systems. Experimental results validate simulation and analytical results.

   Modelling of the Asymmetrical Half-Bridge with Single Output Diode
By T. Tolle; T. Duerbaum [View]
[Download]

Abstract: The BR-TRC2 converter is a member of the family of Asymmetrical Half-Bridge topologies with several advantages, as zero voltage transition (ZVT), one diode per output, limited voltage stress of the switching transistors, utilisation of the transformers leakage inductance, and PWM fixed frequency control. This article presents an introduction to this topology, giving a description and two mathematical models that include losses of the components in practical applications.

   Novel evaluation of transient performance in a DC-DC Flyback conveter
By E. Dallago; A. Danioni; M. Passoni [View]
[Download]

Abstract: In this paper a CCM (Continuous Conduction Mode) Flyback Converter with PWM technique is considered and the performance of the dynamic load regulation investigated. A novel cycle-by-cycle modelization has been developed. This model overcomes the limits of the averaged small signal model when large duty cycle variations during the load transient are considered. Theoretical results were confirmed by experimental ones.
