A simplified IGBT (Insulated Gate Bipolar Transistor) SPICE macromodel, based on its equivalent circuit, is proposed. This macromodel is provided to simulate various mechanisms governing the behavior of the IGBT, and it takes into account specific phenomena limiting its SOA (Safe Operating Area), such as forward and reverse biased SOA, as well as latch-up. The validity of this model is confirmed by comparison between simulation and experimental results as well as the data sheets. This comparison is tested for two IGBT devices showing two different powers and switching speeds, and a good agreement is recorded for both IGBT devices.

In this paper, we present an analysis and a validation of a simulation program with integrated circuit emphasis (SPICE) model for a pulse forming circuit of a high frequency electroporation system, which can deliver square-wave sub-microsecond (100–900 ns) electric field pulses. The developed SPICE model is suggested for use in evaluation of transient processes that occur due to high frequency operations in prototype systems. A controlled crowbar circuit was implemented to support a variety of biological loads and to ensure a constant electric pulse rise and fall time during electroporation to be independent of the applied buffer bioimpedance. The SPICE model was validated via a comparison of the simulation and experimental results obtained from the already existing prototype system. The SPICE model results were in good agreement with the experimental results, and the model complexity was found to be sufficient for analysis of transient processes. As result, the proposed SPICE model can be useful for evaluation and compensation of transient processes in sub-microsecond pulsed power set-ups during the development of new prototypes.

New Process

Epoxy coated reinforcements have been used extensively in bridge decks and substructures to protect against corrosion brought on by de-icing salts or marine environments. They need longer development lengths because of poor bond to concrete and special treatments on sites due to vulnerability of damage during transportation, storage and bending process. A new method of pre-heating of reinforcement before coating process using an IGBT(Insulated Gate Bipolar Transistor) control was applied to improve the bond of epoxy coating to reinforcements. In this paper, the bond-slip properties of newly developed epoxy coated bars are investigated and compared to those of black bars. The direct pull out test according to EN Standard was used with varying the diameters of reinforcements. The experimental results show that the new process is very efficient in increasing bond capacity of epoxy coated bars to concrete comparing those of traditional ones.
