“…Unlike some numerical method which might not be able to find the solution for certain M [25], optimisation algorithm is an intelligent method which guaranteed existence of solutions throughout the full range of M. Among the various optimization based techniques introduced in recent decades, two promising algorithm which have been proven its viability and favourability in SHEPWM problem are GA and particle swarm optimization (PSO) [26]. In recent years, some different optimization algorithms such as bee algorithm (BA) [27] and standard colonial competitive algorithm (CCA) [28] are verified their superiority over GA in terms of better convergence rate. Since this work demands only in acquiring the optimal switching angles and THD minimization regardless of other aspects, GA remains as the preferable option.…”

Abstract--This paper presents a boost-multilevel inverter design with integrated battery energy storage system for standalone application. The inverter consists of modular switched-battery cells and a full-bridge.It is multifunctional and has two modes of operation: the charging mode which charges the battery bank and the inverter mode which supplies AC power to the load. This inverter topology requires significantly less power switches compared to conventional topology such as cascaded H-bridge multilevel inverter, leading to reduced size/cost and improved reliability. To selectively eliminate low-order harmonics and control the desired fundamental component, nonlinear system equations are represented in fitness function through the manipulation of modulation index and the Genetic Algorithm is employed to find the optimum switching angles. A 7-level inverter prototype is implemented and experimental results are provided to verify the feasibility of the proposed inverter design. In recent years, multilevel inverters have been receiving wide attention and becoming hot topologies for renewable energy applications [5], [6]. Multilevel inverters can be classified into three types that are flying- Index Terms--

“…However, considering the large degrees of the equivalent polynomial equations describing the problem of the proposed PSCPWM, this is not an effective approach. Many heuristic algorithms, such as particle swarm optimization (PSO), have been employed for solving transcendental equations [28,29]. Furthermore, some heuristic algorithms have been applied to the modulation methods for multilevel inverters.…”

Cascaded H-bridge multilevel (CHBML) inverters usually include a large number of isolated dc-voltage sources. Some faults in the dc-voltage sources result in unequal cell dc voltages. Unfortunately, the conventional phase-shifted carrier (PSC) PWM method that is widely used for CHBML inverters cannot eliminate low frequency sideband harmonics when the cell dc voltages are not equal. This paper analyzes the principle of sideband harmonic elimination, and proposes an improved PSCPWM that can eliminate low frequency sideband harmonics under the condition of unequal dc voltages. In order to calculate the carrier phases, it is necessary to solve transcendental equations for low frequency sideband harmonic elimination. Therefore, an approach based on the artificial bee colony (ABC) algorithm is presented in this paper. The proposed PSCPWM method enhances the reliability of CHBML inverters. The proposed PSCPWM is not limited to CHBML inverters. It can also be applied to other types of multilevel inverters. Simulation and experimental result obtained from a prototype CHBML inverter verify the theoretical analysis and the achievements made in this paper.

“…In [28], the bee algorithm is applied to solving the problem. In [29], the colonial competitive algorithm is developed to solve the transcendental equations. Until now, it is unfortunate that a way to solve the problem of PSCPWM under the condition of unequal dc voltages has not been described in the literature.…”

High-voltage cascaded H-bridge multilevel (CHBML) inverters usually include many isolated dc voltage sources. Some dc source faults result in a drop in the dc voltage, thereby leading to unequal cell dc voltages. On the other hand, the differences in cell dc source parameters result in unequal dc voltages too. At present, riding through the faults of dc sources and operating under the condition of unequal dc voltages are required to improve the reliability of CHBML inverters. Unfortunately, the conventional phase-shifted carrier pulse width modulation (PSCPWM), which is widely used for CHBML inverters, cannot eliminate low-frequency sideband harmonics when cell dc voltages are not equal. This paper analyzes the principle of sideband harmonic elimination, and proposes an improved PSCPWM based on the particle swarm optimization algorithm. This modulation technique eliminates low-frequency sideband harmonics by calculating and regulating the carrier phases according to different cell dc voltages. The proposed PSCPWM enhances the reliability of the CHBML inverter and extends the range of its application.
