Abstract—The global energy consumption is increasing persistently and need for distributed power generation through renewable energy is essential. To meet the power requirements for consumers without any voltage fluctuations and losses, modeling and design of multilevel inverter with Flexible AC Transmission System (FACTS) capability is presented. The presented inverter is provided with 13-leve...

The developments in power electronics technology have led to the developments in the wind energy conversion system (WECS). The output voltage of the WECS depends on the speed of the wind, which is not constant. Hence, a power conversion unit is required to maintain the output voltage of the WECS constant. This paper presents the design of a boost converter and a voltage controller for maintaini...

Abstract— In this research, a single phase Z-source cascading Multilevel Inverter, Nine-level inverter topologies with a trinary DC sources are offered. The recommended topologies are expanded by cascading a full bridge inverter with dissimilar DC sources. This paper recommends advanced pulse with modulation technique as a switching scheme. In this PWM technology, trapezoidal modulation techniq...

This paper presents a photovoltaic system as a standalone system. The proposed system consists of photovoltaic (PV) module, battery energy storage system (BESS), high frequency transformer, and multilevel inverter (MLI). The MLI consists of two H-bridge single phase inverter per arm (phase) with unequal dc voltages which needs 6 isolated dc sources for the conventional MLI. The relative values ...

in order to reduce the volume and size of distribution power transformer, precise and extended controlling of transformer output, the conventional transformers are replaced by intelligent universal transformers (iuts). in this paper, an iut, typical of iran national grid, with the voltage ratio of 20kv:380 v is designed and simulated. regarding the iut implementation, a cascaded h-bridge invert...

his paper presents a new hybrid cascaded H-bridge multilevel inverter motor drive DTC scheme for electric vehicles where each phase of the inverter can be implemented using a single DC source. Traditionally, each phase of the inverter requires � DC source for 2� + 1 output voltage levels. In this paper, a scheme is proposed that allows the use of a single DC source as the irst DC source which w...

An active power filter implemented with multiples single-phase full bridge voltage-source inverters connected in series (known as cascaded hybrid asymmetric multilevel inverter or binary multilevel VSI) is presented and analyzed in this paper. The proposed active power filter is aimed to compensate current harmonic components in medium and high voltage power distribution systems. A control sche...
