“…For example, energy storage elements such as the ultracapacitor, battery, ywheel etc can be used as storage devices by connecting them to the dc-link [66,44,67,68]. For renewable energy source applications, the battery and the ultracapacitor can be used as storage elements to improve the reliability and the stability of the grid connection [62,44,69,63,70,71,72].…”

“…If the battery is used, this converter is used to control the state of charge with a state control for optimum charging, while the ultracapacitor is used to regulate the dc-link voltage [40,71,79]. Other than these strategies it can also use the inner loop current control, the other voltage loop that been proposed in [67,72,76], the nite state machine in [64], or the dynamic evolution control in which the switching angle was calculated by [69]; these are able to control the power ows from the bidirectional converter. In [80] it has been suggested to use the state of charge for the ultracapacitor for the power ow process.…”

Currently, renewable energy sources are the main driver for future electricity generation. This trend is growing faster in the developed countries in order to reduce the green house e ect and also in response to the limited supply of oil, gas and coal which are currently the major sources for electric generation. For example, the main renewable energy sources are from wind energy and solar energy but these energies are only available to those countries that are exposed to these resources. In this thesis an alternative energy source is investigated where it can be generated from the moving objects or in form of kinetic energy. The idea is to convert the kinetic energy during landing aircraft into electrical energy which it can also be stored and transferred to the existing electrical network. To convert this kinetic energy to electrical energy, the linear generator (LG) and uncontrolled recti er have been used for energy conversion. The LG have been modelled in 3-phase model or in dq model and combined with the diode recti er that is used to generate the dc signal outputs. Due to the uncontrolled recti er the electrical outputs will have decaying amplitude along the landing time. This condition also happen to the LG outputs such as the force and the power output. In order to control these outputs the cascaded buck-boost converter has been used. This converter is responsible to control the output current at the recti er and also the LG output power during landing to more controllable power output. Here, the H ∞ current control strategy has been used as it o ers a very good performance for current tracking and to increase the robustness of the controller. During landing huge power is produced at the beginning and when the landing time is increased, the generated input power from LG is reduced to zero. Due to this, the energy storage that consits of ultracapacitor, bidirectional converter and boost converter are usedin order to store and to release the energy depends on the input power source and load grid power. The voltage proportional-integral (PI) control strategy has been used for both the converters. The last part is to transfer the energy from the source and at the ultracapacitor to the load by using the inverter as the processing device. The power controller and current controller are used at the inverter in order to control the power ow between the inverter and the grid. This is when the reference power is determined from the load power in order to generate the reference current by using the voltage oriented controller (VOC), while the H ∞ current controller is used to regulate the inverter current in order to inject the suitable amount of current that refer to the load power. Finally, a complete energy recovery system for landing aircraft with the grid connection have been put together to make the whole system to be as a new renewable energy source for the future electricity generation.

“…Step down dc-dc converters are constantly used as MPPT systems to avoid the power losses created in PV generation systems [6][7][8] For effective battery charging and discharging system, uninterruptible and auxiliary power supplies, several bidirectional dc-dc converters have been proposed. Bidirectional dc-dc converters with high-frequency isolation transformer based topologies [9][10][11][12] are most likely structures.…”

This paper presents a soft switching bidirectional buck-boost converter for battery charging and discharging systems. The proposed method comprises of Inductance Capacitance Diode combination of the bidirectional dc-dc converter with one more electric switch is presented to accomplish high efficiency, high conversion ratio and maximum output power compared to the other bidirectional converters. It works in both steps up and steps down conversions. The proposed converter has alleviated the switching stress problems in the conventional bidirectional dc-dc converter. It suppresses the switching losses by zero voltage and zeroes current turn ON and OFF all switches. The complete steady-state analysis of the proposed bi-directional converter has described with its operating modes. Design consideration of parameters also presented to realize the converter characteristics. The switching stress on the power semiconductor devices is given, and the comparisons between the proposed technique and other bidirectional converters are illustrated with some results. Finally, the experimental prototype of 20 kHz, 315 W output power converter developed, and its feasibility verified through computer simulation results.

DC/DC switching converters are widely used in numerous appliances in modern existence. In this paper, the dynamic and transient response of phase shift series resonant DC/DC converter are improved using hybrid particle swarm optimization tuned fuzzy sliding mode controller under starting and load step change conditions. The aim of the control is to regulate the output voltage beneath the load change. The model of the hybrid particle swarm optimization tuned fuzzy sliding mode controller is implemented using Sim Power Systems toolbox of MATLAB SIMULINK. Performance of the proposed dynamic novel control under step load change condition is investigated.
