In this paper a fault-tolerant isolated dc-dc converter is proposed for shipboard power applications. In this topology, an active 5-level T-type converter is used on the primary and secondary sides of a high-frequency transformer. The operation of the proposed converter is optimized based on minimizing the losses. A fault-tolerant analysis is carri...
In this article, a bidirectional isolated dc–dc converter is proposed for application in shipboard power systems. In this topology, an active 5-level T-type converter is used on the primary and secondary sides of a high-frequency transformer. The operation of the proposed converter is optimized based on minimizing power losses. For the optimization...
Cascaded multilevel inverters (MLIs) have been proposed that utilise transformers in the basic unit. The proposed inverters primarily serve to step up the input voltages in addition to using lower number of components in comparison to traditional MLIs. In order to generate all voltage levels (even and odd) at the output, three different algorithms...
In this paper, a modified DC/DC high step-up converter is proposed. Maximum power point tracking, which is very important in photovoltaic (PV) applications, is dependent on the input current ripple of the PVs. In some other converters where the input current ripple is high, the maximum power point cannot track properly. Therefore the proposed conve...
A new three-phase hybrid multilevel inverter configuration is proposed. The proposed inverter is modular and consists of three single-phase H-bridge inverters, one three-phase H-bridge inverter and auxiliary modules for increasing the number of output voltage levels. The performance of the proposed inverter has been compared with some of the common...
Multilevel converters have found many applications within renewable energy systems thanks to their unique capability of generating multiple voltage levels. However, these converters need multiple DC sources and the voltage balancing over capacitors for these systems is cumbersome. In this work, a new grid-tie multicell inverter with high level of s...
A novel single-phase single-stage transformerless grid-connected current source inverter is proposed for photovoltaic system application. The proposed inverter consists of one inductor, four unidirectional switches and two diodes. The proposed inverter does not suffer from ground leakage current since that the PV panel and the gird utilize common g...
A novel flying capacitor inverter has been proposed that utilizes the transformer in the basic unit. In order to generate all the voltage levels (even and odd) at the output, the magnitude of the capacitor's voltage is controlled. Also a new control strategy to generate maximum output voltage levels is proposed. The proposed control strategy is cap...
In this paper, maximum power point tracking (MPPT) control method is developed for the transformer-based inverter with high output voltage gain. The proposed control strategy is capable of tracking the maximum power point of photovoltaic under the change of radiation and temperature. Also the operation of the inverter and control strategy is analyz...
In this paper, two various transformer-based inverters are proposed. The proposed inverters consist of one center-tap transformer, two bidirectional switches and three unidirectional switches. The proposed inverters are capable of increasing the input voltage according to the winding turn-ratio of the transformers and isolating input DC sources wit...
This paper proposes an improved structure for none-isolated Multi-Input (MI) high step-up dc-dc converters. The bidirectional power flow operation can also be provided for the proposed topology. Unlike most of none-isolated none-coupled inductor based topologies, the proposed topology can produce high voltage gains with low voltage stress on the sw...
In this paper, an improved Cascaded Multi-Level Inverter (CMLI) topology which can be “symmetric” or “asymmetric” is proposed. The improved topology can produce higher number of levels using lower number of components. Higher number of levels leads to generation of a high quality with low Total Harmonic Distortion (THD) output voltage waveform. To...
Multilevel inverters generate high-level voltage with high quality and low-harmonic distortion, and these unique properties have increased their applications in renewable energy sources. However, these inverters require several passive components and a complex pulse width modulation (PWM) control method. Besides, they suffer from voltage balancing...
A 15-level flying capacitor multi-cell based inverter with new control method is proposed. The main benefit of this topology is minimising the number of components (switches, insulated-gate bipolar transistor (IGBTs), diodes, flying capacitors and DC sources with minimum variety number) that are used for producing the same number of output voltage...
