This book was released on 2012 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed energy resources like solar power (PV Panels) are usually connected to the AC grid through a single phase voltage source inverter (VSI). The major drawback associated with single phase grid tie inverters is the double frequency component of the grid that appears on the DC bus link. Large electrolytic capacitors are generally employed in the inverters to eliminate the ripple component. However, their bulkiness and relatively short lifetime are motivational factors to replace them with small film capacitors. This paper presents a synchronous boost/buck based active power decoupling circuit in parallel with the dc-bus link capacitor and discusses the different types of control strategies implemented. Simulation results are presented for each control technique and it is shown that the ripple on the DC bus link is largely reduced due to inclusion of this circuit along with an expected extension of the lifetime due to the reduction in the amount of dc-bus capacitance used.

Book excerpt: Continuous cost reduction of photovoltaic (PV) systems and the rise of power auctions resulted in the establishment of PV power not only as a green energy source but also as a cost-effective solution to the electricity generation market. Various commercial solutions for grid-connected PV systems are available at any power level, ranging from multi-megawatt utility-scale solar farms to sub-kilowatt residential PV installations.

This Special Issue collects the latest developments in the field of power electronic converter topologies, control, design, and optimization for better energy yield, power conversion efficiency, reliability, and longer lifetime of the small-scale PV systems. This Special Issue will serve as a reference and update for academics, researchers, and practicing engineers to inspire new research and developments that pave the way for next-generation PV systems for residential and small commercial applications.

Download or read book Resonant Micro Inverters for Single Phase Grid connected Photovoltaic Systems written by and published by . This book was released on 2015 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses the design and implementation of micro-inverters for grid-connected single-phase photovoltaic (PV) systems. Despite the existing research issues concerning Micro-inverters, they have recently become very attractive due to their modularity and capability of independent maximum power point tracking (MPPT). The complexity in the design of micro-inverters stems from strict grid connection standards and high expectations of compactness, large amplification gain, high efficiency over a wide range of operating conditions and excellent output power quality. Moreover, since micro-inverters are exposed to a wide temperature range, the reliability and life-time of this technology are major problems. The main limiting factor in the life-time of micro-inverters is the use of large electrolytic capacitors for power decoupling. New circuit configuration and control structures to design a compact and efficient micro-inverter with high quality and robust output power injection capabilities are introduced in this thesis. In the proposed topology electrolytic capacitors are eliminated, removing the obstacles in achieving a durable and reliable design. To achieve a compact design, the proposed micro-inverter consists of a soft-switching high frequency resonant converter at the input and a hard-switching lower frequency inverter with a high order filter at the output. Small and large signal models of the resonant converter are obtained to design controllers. A new optimal controller and a design method are also proposed for the inverter that yield robust performance with a high quality output in the presence of grid voltage harmonics, impedance uncertainties and frequency changes. Furthermore, using a new nonlinear control strategy, a direct instantaneous power control method is proposed to achieve fast active and reactive power injections into the grid without using the measurement or calculation of active and reactive powers. A comprehensive steady state analysis is carried out to arrive at a final design that ensures optimum responses for all operating conditions. Moreover, for all proposed controllers, stability analysis is performed to guarantee sufficient stability margins accounting for uncertainties and nonlinearities. Analytical, simulation and experimental results are presented to verify the effectiveness of the proposed methods.

Novel PWM and Multilevel Inverters The book first covers traditional pulse-width-modulation (PWM) inverters before moving on to new quasi-impedance source inverters and soft-switching PWM inverters. It then examines multilevel DC/AC inverters, which have overcome the drawbacks of PWM inverters and provide greater scope for industrial applications. The authors propose four novel multilevel inverters: laddered multilevel inverters, super-lift modulated inverters, switched-capacitor inverters, and switched-inductor inverters. With simple structures and fewer components, these inverters are well suited for renewable energy systems.
