AbstractThe high electrical stresses in the Electrical Insulation Systems of machines fed by pulse width modulation (PWM) inverters remain a limitation of the lifetime. The stress is caused by repetitive over voltages caused by the short switching times of the PWM inverter power electronic circuit. This paper provides measurements made on an industrial drive connected to the grid with standard cables that include a ground connection wire, following the current standards. The phase-to-phase, phase-to-neutral, and neutral-to-ground voltages are measured focusing on short and repetitive voltage spikes. The causes of these voltage spikes are analyzed using a high frequency equivalent circuit of the whole drive, including the earthing system. The simulations are made with the well-known SPICE circuit simulator. This study focuses on the common-mode currents flowing in the earthing connections and its influence on voltage spikes. A solution that can reduce significantly the phase-to-neutral voltage spikes is proposed.

<p align="justify">The electronic circuit engineering learning processes generally requires specific infrastructures which sometimes constrained to cost factors in the procurement. Circuit simulator could be an alternative as electronic circuit engineering learning tool. Architectural simulation provides designers the ability to quickly examine a wide variety of design choices. The recent trend in system design toward architectures that react to circuit-level phenomena has outstripped the capabilities of traditional cycle-based architectural simulators. In this paper, a simulator that incorporates a circuit modeling capability, permitting architectural-level simulations that react to circuit characteristics (such as latency, energy, power brightness, or current draw) on a cycle-by-cycle basis is presented. As for learning purpose, circuit template and pre-built circuits for many categories are provided. The environment enables process visualization and simulation of analog and digital circuits. The system enables the creation of many laboratory exercises, which offer students opportunities to follow visually characteristic processes in analog and digital circuits. At this research, Rational Unified Process (RUP) software process model and Object Oriented Programming (OOP) are implemented.<br />Keywords: architectural simulation, circuit simulation, learning, RUP, OOP</p>

This paper deals with the theoretical and experimental study of an electromechanical system (EMS) actuated by a chemo-inspired oscillator, namely, the Brusselator oscillator. The modeling of such a system is presented. Theoretical results show that the displacement or flexion of the EMS undergoes spiking oscillations. This kind of oscillation is due to the transfer of the Brusselator electronic circuit signal to the mechanical arm. The theoretical results are confirmed by an experimental study with a good qualitative agreement.
