Power converters with LCL filters have been widely adopted in systems, e.g., micro-energy grid-tied renewable energy etc. Such a system forms high-order xmlns:xlink="http://www.w3.org/1999/xlink">multiple input and multiple output (MIMO) dynamic system, requiring complicated active damping ...

State-of-the-art ultra-fast battery chargers for electric vehicles simultaneously require high efficiency and power density, leading to a challenging converter design. In particular, the grid-side filter, which ensures sinusoidal current absorption with low pulse-width modulation (PWM) harmonic content, can be major contributor overall size losses. Therefore, this paper proposes complete analys...

This paper presents a distributed generation system using power static converter connected to mains through an LCL filter. The control law is based on state feedback. modelled in synchronous reference allowing the use of integral actions for eliminating state-steady errors active and reactive powers DC voltage controls. feedback gains are calculated Linear Quadratic Regulator methodology starti...

A novel approach for VSI with an LCL output filter controller design for microgrids operating in grid-connected mode is presented in this paper. The controller structure is based on a multiloop control configuration in which the inner control loop is responsible for current regulation and the outer control loop generates the reference currents based on preset active and reactive power injection...

This article deals with discrete-time state-space current controllers for three-phase grid converters equipped an LCL filter. The integral action in the controller can be implemented either using integrator or a disturbance observer. results show that disturbance-observer-based and integrator-based become mathematically equal if feedforward gains are selected to equal, zero is placed cancel pol...

(ii) the DNA of Ch-LCL contained sequences homologous to approximately 35 to 45% of human EBV; (iii) Ch-LCL contained an intranuclear antigen, Ch-NA, that could be identified with some chimpanzee or orangutan serum in anticomplimentary immunofluorescence assays; and (iv) treatment of Ch-LCL with iododeoxyuridine resulted in expression of new antigenic activity that reacted with EA+ but not EAhu...

Epstein-Barr virus (EBV) super-enhancers (ESEs) are essential for lymphoblastoid cell (LCL) growth and survival. Reanalyses of LCL global run-on sequencing (Gro-seq) data found abundant enhancer RNAs (eRNAs) being transcribed at ESEs. Inactivation of ESE components, EBV nuclear antigen 2 (EBNA2) and bromodomain-containing protein 4 (BRD4), significantly decreased eRNAs at ESEs -428 and -525 kb ...

On the Language Design and Semantic Foundation of LCL a Larch C Interface Speci cation Language The specialization of a speci cation language to a particular programming lan guage is an important characteristic of module interface speci cation languages MISL s The only well developed MISL s are the Larch interface languages and among these LCL a Larch C interface speci cation language would see...

INTRODUCTION: Posterior tibial tendon dysfunction (PTTD) is the most common cause of the adult flatfoot and is treated with a variety of operations such as tendon transfers, ligament reconstruction, osteotomies, and arthrodeses. Lateral column lengthening with a calcaneocuboid fusion (LCL) (Fig. 1) has been reported for treatment of PTTD in adults (1) to correct the deformity, while minimizing ...
