Book Description
The objective of this thesis work is devoted to the design and control of a DC/DC boost converter for Fuel Cell Electric Vehicle (FCEV) application. A 6-phase Interleaved Boost Converter (IBC) based on Silicon Carbide (SiC) semiconductors and inversed coupled inductors of cyclic cascade structure is proposed. The input current ripple is reduced significantly and the lifespan of Polymer Electrolyte Membrane Fuel Cell (PEMFC) can be extended. Low power losses, good thermal performance and high switching frequency have been gained by the selected SiC-based semiconductors. The volumes of passive components (inductors and capacitors) are reduced. Thanks to the inverse coupled inductors, the core losses and copper losses are decreased and the compact magnetic component is achieved.Sliding-Mode Control (SMC) strategy is developed due to its high robust to parameter variations. on-line Electrochemical Impedance Spectroscopy (EIS) detection functionality is successfully integrated with SMC. No additional equipment and sensor is required.The real-time Hardwar In the Loop (HIL) validation of the proposed converter is achieved by implement the power part into the FPGA and the control into the microprocessor in the MicroLabBox prototyping system from dSPACE. The comparison between off-line simulation and HIL validation demonstrated the dynamic behavior of the proposed converter and validated the implementation of the control into a real time controller before future tests on experimental test bench.

Book Description
Hybrid electric vehicles (HEVs) are driven by at least two prime energy sources, such as an internal combustion engine (ICE) and propulsion battery. For a series HEV configuration, the ICE drives only a generator, which maintains the state-of-charge (SOC) of propulsion and accessory batteries and drives the electric traction motor. For a parallel HEV configuration, the ICE is mechanically connected to directly drive the wheels as well as the generator, which likewise maintains the SOC of propulsion and accessory batteries and drives the electric traction motor. Today the prime energy source is an ICE; tomorrow it will very likely be a fuel cell (FC). Use of the FC eliminates a direct drive capability accentuating the importance of the battery charge and discharge systems. In both systems, the electric traction motor may use the voltage directly from the batteries or from a boost converter that raises the voltage. If low battery voltage is used directly, some special control circuitry, such as dual mode inverter control (DMIC) which adds a small cost, is necessary to drive the electric motor above base speed. If high voltage is chosen for more efficient motor operation or for high speed operation, the propulsion battery voltage must be raised, which would require some type of two-quadrant bidirectional chopper with an additional cost. Two common direct current (dc)-to-dc converters are: (1) the transformer-based boost or buck converter, which inverts a dc voltage, feeds the resulting alternating current (ac) into a transformer to raise or lower the voltage, and rectifies it to complete the conversion; and (2) the inductor-based switch mode boost or buck converter [1]. The switch-mode boost and buck features are discussed in this report as they operate in a bi-directional chopper. A benefit of the transformer-based boost converter is that it isolates the high voltage from the low voltage. Usually the transformer is large, further increasing the cost. A useful feature of the switch mode boost converter is its simplicity. Its inductor must handle the entire current, which is responsible for its main cost. The new Z-source inverter technology [2,3] boosts voltage directly by actively using the zero state time to boost the voltage. In the traditional pulse width modulated (PWM) inverter, this time is used only to control the average voltage by disconnecting the supply voltage from the motor. The purpose of this study is to examine the Z-source's potential for reducing the cost and improving the reliability of HEVs.

Book Description
The high demand of energy efficiency has led to the development power converter topologies and control system designs within the field of power electronics. Recent advances of interleaved boost converters have showed improved features between the power conversion topologies in several aspects, including power quality, efficiency, sustainability and reliability. Interleaved boost converter with multi-phase technique for PV system is an attractive area for distributed power generation. During load variation or power supply changes due to the weather changes the output voltage requires a robust control to maintain stable and perform robustness. Connecting converters in series and parallel have the advantages of modularity, scalability, reliability, distributed location of capacitors which make it favorable in industrial applications. In this dissertation, a design of æ-synthesis controller is proposed to address the design specification of multi-phase interleaved boost converter at several power applications. This thesis contributes to the ongoing research on the IBC topology by proposing the modeling, applications uses and control techniques to the stability challenges. The research proposes a new strategy of robust control applied to a non-isolated DC/DC interleaved boost converter with a high step voltage ratio as multi-phase, multi-stage which is favorable for PV applications. The proposed controller is designed based on æ-synthesis technique to approach a high regulated output voltage, better efficiency, gain a fast regulation response against disturbance and load variation with a better dynamic performance and achieve robustness. The controller has been simulated using MATLAB/Simulink software and validated through experimental results which show the effectiveness and the robustness.

Book Description
The focus of this thesis is to design a DC-DC quasi-soft switched boost converter suitable for fuel cell applications. Study of electrical output characteristics of fuel cells was necessary for this purpose. A number of experiments were conducted to study the steady-state and transient response of fuel cell system under various load dynamics. The results of these findings were necessary for the next phase of the project which was to design a reliable and high-performance regulated DC-DC converter. The design goals were realized with a soft-switching boost converter (implementation of zero voltage switching (ZVS) and zero current switching (ZCS) schemes) that employs a simple and effective control scheme. Key benefits of soft-switching such as high efficiency (at high switching frequencies), reduced EMI, and decreased power stress on semiconductor devices were verified. Apart from these benefits, the point that is highlighted is achieving decreased fuel cell output current ripple at higher frequencies. This is of significance because fuel cell systems prefer lower levels of current ripple which ultimately results in prolonged life time of the system. In addition, operating at high frequencies will allow for designing of high power density converters to match the high power density of fuel cells.
