This paper investigated and demonstrated an electric drive topology with inherently high reliability improved performance. The combines a five-phase combined star-pentagon synchronous reluctance machine (SynRM) power electronic “matrix” converter without vulnerable electrolytic capacitors, which are often point of failure conventional drives. is suitable for harsh environments, possibly ambient...

In this paper, to solve the hard-switching operation problem and lack of existing a bidirectional power flow path from output energy storage device conventional three-port converter, new soft-switched multi-port converter is proposed. A large number switches, different paths which vary in each operating mode, changing outputs their levels are some challenges provide soft-switching conditions co...

Most models of Bidirectional associative memories intend to achieve that all trained pattern correspond to stable states; however, this has not been possible. Also, none of the former models has been able to recall all the trained patterns. In this work we introduce a new model of bidirectional associative memory which is not iterative and has no stability problems. It is based on the Alpha-Bet...

Multilevel inverter had been paid a lot of attention from the academia and research community in recent times due to its role high medium power applications. In this paper, detailed survey is made on recently designed multilevel find suitability inverters for particular Research performed various types such as: Symmetric, asymmetric, hybrid modularized order identify issues generating more leve...

In recent times, multilevel inverters (MLIs) have become very popular for commercial and industrial applications. Here, an eleven-level inverter its power flow control are presented. The presented topology has a lesser component count than other existing topologies, thus reducing the devices overall cost of inverter. This comprises six bidirectional switches, two DC sources, one four-quadrant s...

A three-phase dual-active-bridge (3p-DAB) converter is an attractive topology for bidirectional power conversion in high-power applications. However, conduction and switching losses are two main loss mechanisms that severely affect its efficiency performance, adoption of any single modulation scheme or cannot minimize these over a wide operating range. For this purpose, reconfigurable the 3p-DA...

Miniaturised piezoelectric devices are emerging energy harvesting sources that appropriate for various implantable and wearable applications. However, these exhibit considerable internal resistance due to their impedance, which leads self-start low-energy conversion failures. This paper describes a dual-stage boost converter circuit by facilitating self-powering features boosting the low voltag...

This paper proposes a novel three-phase topology with reduced component count for low- and medium-voltage systems. It requires three bidirectional switches twelve unidirectional producing four-level voltages without using flying capacitors or clamping diodes, reducing the size, cost, losses. Removing diodes allows it to simplify control algorithms increase reliability, efficiency, lifetime. A m...

The CLLC resonant converter is a promising candidate for high efficient, bidirectional power transfer applications, such as vehicle-to-grid on-board charger and hybrid vehicle dc–dc converter. Nevertheless, the analysis of still remains challenging because its complex multiresonant nature several storage elements. In this article, circuit method based on change variables presented...
