A new feeding concept for electrical transportation systems is presented, based on supercapacitive energy storage. Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy supercapacitors can store is low and does not allow large vehicle autonomy. Because supercapacitors have the property to be re-loadable in a few seconds, a sequential supply system has been developed, considering repetitive feeding at the stops. To solve the problem of the high power amount needed to reach short refill times, a solution is proposed, which consists of using an intermediary supercapacitive tank placed at fixed stations, which is refilled between the bus arrivals with a much lower power. In addition to the description of the needed power electronic converters, theoretical and experimental results are presented, defining the controlled profile of the instantaneous power level, in order to achieve a fast energy transfer between two supercapacitive tanks.

This paper presents a modified power supply system based on the current alternating current (AC)-fed railways with neutral zones that can further improve the eco-friendliness and smart level of railways. The modified system complements the existing infrastructure with additional energy-storage-based smart electrical infrastructure. This infrastructure comprises power electronic devices with energy storage system connected in parallel to both sides of each neutral zone in the traction substations, power electronic devices connected in parallel to both sides of each neutral zone in section posts, and an energy management system. The description and functions of such a modified system are outlined in this paper. The system allows for the centralized- and distributed-control of different functions via an energy management system. In addition, a control algorithm is proposed, based on the modified system for regenerative braking energy utilization. This would ensure that all the regenerative braking energy in the whole railway electrical system is used more efficiently. Finally, a modified power supply system with eight power supply sections is considered to be a case study; furthermore, the advantages of the proposed system and the effectiveness of the proposed control algorithm are verified.

Power electronic transformer (PET) which has a big potential application value in smart grid is an electrical power transformer device adopting power electronic converter and high frequency switch transformer. A new PET with power factor correctors (PFC) is proposed in this paper. Due to high power level of PET, PFC should have a high power level as well. Therefore, the multi-phase interleaved PFC is employed. The paper describes the one cycle control principle, proposes a current synthesis method based on IGBT current, and then analyses the relationship between ripple current and duty cycle of IGBT. In addition, the whole PFC system is simulated completely by means of Matlab/Simulink. In order to verify the theoretical analysis and simulation analysis, a four-phase interleaved PFC with a rated output power of 8.0kW is designed and implemented based on the an analog control chip. The obtained results show that the interleaved PFC by means of one cycle control and current synthesis is feasible, capable of reaching a good suppression effect of ripple current.

Power Electronic Converter

The residential and commercial buildings are going green to reduce the carbon footprint. To improve the energy efficiency of the buildings, the Internet of Things can be used in conjunction with power electronic converters to improve the performance of energy efficient buildings. The distributed generation for the buildings mainly consists of battery energy storage, wind generator, solar PV panels along with the national utility grid. So, the power/energy from renewable sources can be efficiently managed by the power electronics converter. Mainly the power electronic converters are two categories one for the energy utilization side and the second is the generation, transmission, and distribution of the electrical energy. The power electronic converter has been developed to address the multiple source’s communications at the central converter, which reduces the utility bill payment to the energy (grid) suppliers and depends fully on the renewable energy sources along with the battery energy storage. To achieve this a novel power electronic converter has been proposed. This directly connects the PV panels with the semiconductor devices, passive components like inductors and capacitors along with the battery energy storage. The resultant output is directly feeding o the utility grid and simultaneously commercial home. A detailed mathematical analysis has been carried out along with the novel switching algorithm has been proposed. The simulation is performed in the MATLAB Simulink to validate the operation/working of the proposed converter. An experimental prototype 500 watt has been developed to test the mathematical validity and a suitable control algorithm has been developed for the proper operation.
