The resulting structures are generally very attached to a specific technology and are not very new. To avoid this, a functional description is proposed here in order to take into account the technological aspect very later in the design process. In such an approach, specifications are mainly defined by qualitative criteria, which implies numerous problems developed in the paper. Here, an example of a simple functional graph building is presented to show how a coherence checking can be automatically carried out thanks to the functional approach proposed in this paper. In the future, our final goal is to build an expert system for static converter structure design.","PeriodicalId":250682,"journal":{"name":"COM.P.EL.98.

In these studies, converters are usually modeled as a set of real or idealized switches, which may result in long execution times and possible convergence problems, particularly in complex circuits. This paper proposes the use of macromodels to simulate active filters. The macromodels are based on converter switching functions rather than actual circuit components, and they are well suited for steady state and large signal transient analysis at the system level. In this approach, the converters are simulated as multiport networks avoiding the physical nonlinear micromodels associated with power switches. Computer memory and execution times required for the simulation of the power circuit are thereby significantly reduced. The procedure also allows rapid design of filter components, in particular passive elements such as inductors and capacitors. Complete examples of typical shunt filters are given to illustrate the effectiveness of the proposed models.","PeriodicalId":250682,"journal":{"name":"COM.P.EL.98.

Extended use of mixed mode device circuit simulations allows the analysis of diode behavior in realistic working conditions. In the paper the emphasis is given on the effect of the position and of the extension of the reduced lifetime region on diode performance. The low lifetime region, the result of complex damage in the epilayer, is approximated with a rectangular shape in the simulator, and is defined by its thickness, position and amount of lifetime reduction. The simulations show that the optimal position for the low-lifetime region is at the beginning of the epilayer region on the anode side, while the optimal thickness of the low lifetime region depends on the amount of lifetime reduction. The local lifetime control design technique is shown to be effective in reducing the turn-off time and increasing diode softness with a little worsening of on-state voltage drop. It is shown that the trade-off curve obtained by diodes using local lifetime control is better than the one achieved with lifetime killing in the whole epilayer region.","PeriodicalId":250682,"journal":{"name":"COM.P.EL.98.

The results for a basic PWM boost converter running open-loop under voltage-mode control show that perturbing the control signal or input voltage at frequencies close to the switching frequency or its harmonics can give rise to significant aliased components at the low difference frequency. The simulation results reinforce the concerns raised in regarding the limitations of small-signal frequency-response information in frequency ranges where aliasing is significant.
