Power-electronics simulation

Steven M. Sandler is the founder of AEi Systems, LLC, the world leader in SPICE modeling and worst case circuit analysis since 1995. He has developed and taught courses at Motorola University and has published many books and articles on circuit simulation for McGraw-Hill and Power Electronics, PCIM, and PEIN magazines. 

Bateman and coworkers report a comparative analysis of six different hydraulically powered compaction simulators manufactured by a variety of vendors (Table 1), In their round-robin study, they found that the compaction simulators were comparable when operated within a moderate compression stress range of 50-2(X)MPa. However, at higher pressures, correction factors needed to be applied because of elastic distortion and differences in loading characteristics of the hydraulic systems (5). These results are not surprising since like rotary tablet presses, compaction simulators are not perfectly rigid. Therefore, compaction simulators should be properly calibrated (including corrections for mechanical flexure and electronic noise) to ensure the collection of quality experimental data. 

Foam was demonstrated to successfully humidify dry inlet air to 87% saturation at 60°C using a simulated power electronic device. 

A mathematical model for heat transfer in foams was developed, which can simulate power electronics cooling by fluid flow through the foam. 

The small example systems considered in this chapter are widely used basic components of power electronic systems. In power electronics, it is common to model the fast switching semiconductor devices that use various types of transistors, diodes, or thyristors simply as ideal or non-ideal switches although more sophisticated transistor models can be used and are used depending on the application and the purpose of a simulation study.

The solutions are the following (1) expansion of the electronics simulator to power-system analysis by developing some modes of power apparatuses and (2) expansion of the power-system simulator, such as the EMTP, by developing some modes of semiconductor devices. In this section, the latter method is employed [1, 2, 3, 4, 5, 6, 7-8]. 

The switching characteristic of MOSFET is expressed by the parameters shown in Table 4.10. Although the physical behavior of a MOSFET is too complicated for an EMTP simulation, the operational characteristic can be reproduced with satisfactory accuracy from the viewpoint of the numerical simulation of a power system including power-electronics apparatuses. A simple representation method of the dynamic characteristic is proposed in this... 

The EMTP has been widely used for estimating transient overvoltages on a power system. In a power-electronics field, the prediction of temperature rise and overvoltages in the switching circuit is one of the important goals of numerical simulations. The result provides valuable information for designing power-electronics apparatuses. 

A hybrid system consisting of a fuel cell and lithium-ion battery has been successfully introduced in a pulse power load simulation similar to military electronics and communications equipment. The hybrid consists of a 35 W proton exchange membrane fuel cell stack in parallel with a lithium-ion battery. Two cycling regimes are utilized. Each consists of a baseline load for 9 min followed by a higher pulse load for 1 min. One regime consists of 20 W (baseline)/40 W (pulse) load, whereas the second is 25 W/50 W. Under both scenarios, the hybrid provides significantly enhanced performance over the individual components tested separately.
