A new numerical method for semiconductor device simulation is presented. The additive decomposition method has been successfully applied to Burgers' and Navier-Stokes equations governing turbulent fluid flow by decomposing the equations into large-scale and small-scale parts without averaging. The additive decomposition (AD) technique is well suited to problems with a large range of time and/or space scales, for example, thermal-electrical simulation of power semiconductor devices with large physical size. Furthermore, AD adds a level of parallelization for improved computational efficiency. The new numerical technique has been tested on the 1-D drift-diffusion model of a p-i-n diode for reverse and forward biases. Distributions of φ, n and p have been calculated using the AD method on a coarse large-scale grid and then in parallel small-scale grid sections. The AD results agreed well with the results obtained with a traditional one-grid approach, while potentially reducing memory requirements with the new method.

At present, small-scale grid-connected PV system is increasingly developed and used in many households. These small-scale PV system are often connected to grid using microinverter, because its advantages are low maintenance investment costs, ease of installation and operation and do not cause environmental pollution. The content of the article focuses on power quality analysis of the non-stored grid-connected PV system using microinverter. The research method in the paper is based on experiments on models and laboratory measurements. The analytical results will assess the power quality of grid-connected PV system using microinverter, thereby managers and operators to take measures to improve the power quality of the electrical system with grid-connected PV system.
