“…GSSA method is taken out from Fourier Transformations for a non-periodic signal [28][29][30]. The method is based upon a principle that an x(t) waveform between infinite time interval of (t-T, t] can be approached with arbitrary accuracy using finite coefficients of Fourier Transformation [31,32].…”

This work aims to improve well known generalized averaged models for mathematical modelling of parallel active filter (PAF) with voltage supply. To achieve this task, the method is adopted to generalized state space averaging (GSSA) method. Non-linearity of the system is removed by using GSSA method. Relation between the state variables of the system is expressed by linear equations. An exact and fast approximation of the system parameters is achieved. Non-linearity of real elements that causes many problems such as long execution time, divergence, and huge produced files do not exist thanks to the method. A single phase full-bridge voltage supply inverter is proposed as a parallel active filter. A diode rectifier with RL load is used as a nonlinear load. In this study, simulation results of parallel active filter mathematically modeled with GSSA model are compared to real-time designed simulation results of parallel active filter realized power simulation with PSIM software. In the results obtained through mathematical models with real model has been observed that a good match.

“…To overcome this difficulty it is usually made use of average model (widely used for modeling static converters) [11][12]; it supposes that the switching period is very small compared to the system dynamics. In our case, this is largely justified.…”

Abstract. Multilevel converters are becoming increasingly used in many industrial applications due to the many advantages that they offer. The improvements in the output signal quality, lower Total Harmonic Distortion (THD) and many other properties make multilevel converters very attractive for connecting photovoltaic generators to medium voltage grid directly or to be used in a local power supply. In this paper, we focus on the implementation of a three-phase five-level diode clamped inverter and design of a performing nonlinear controller using the Backstepping approach. The control objective is to generate, at the system output, sinusoidal three-phase voltages with amplitude and frequency fixed by the reference signal independently of load variations. The performance study of the multilevel inverter and the designed controller are made by simulations in Matlab/Simulink environment.

“…A power converter circuit is made of many devices. Many abstraction models have been developed and detailed in literature (Middlebrook, 1976), (Cùk, 1977), (Krein, 1990), (Lee, 1985), (Sanders, 1991), (Smedley, 1994), (Ben-Yaakov, 1995), (Lai, 1995), (Maksimovic, 1998), (Xu, 1994), (Olivier, 2000). A functional view of a power converter has been proposed as the so-called average model.…”
