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.

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.

The operational principle of a classical converter of AC into AC energy is described in Section 1 Chapter 3. It includes an explanation of the basic idea on which the operation of the further down studied power electronic converters is based. The basic indicators of a power electronic converter supplied by an AC power have been studied in Chapter 4. The conclusions made in it according the ways of the increase of the power factor KP are also valid in AC/AC converters. The purpose is to consume current with a waveform as close as possible to a sine wave (with low contents of harmonics) and whose first harmonic to be in phase with the source voltage.
