Abstract-This study develops a high-performance stand-alone photovoltaic (PV) generation system. To make the PV generation system more flexible and expandable, the backstage power circuit is composed of a high step-up converter and a pulsewidthmodulation (PWM) inverter. In the dc-dc power conversion, the high step-up converter is introduced to improve the conversion efficiency in conventional boost converters to allow the parallel operation of low-voltage PV arrays, and to decouple and simplify the control design of the PWM inverter. Moreover, an adaptive total sliding-mode control system is designed for the voltage control of the PWM inverter to maintain a sinusoidal output voltage with lower total harmonic distortion and less variation under various output loads. In addition, an active sun tracking scheme without any light sensors is investigated to make the PV modules face the sun directly for capturing the maximum irradiation and promoting system efficiency. Experimental results are given to verify the validity and reliability of the high step-up converter, the PWM inverter control, and the active sun tracker for the high-performance stand-alone PV generation system. Index Terms-Active sun tracking scheme, adaptive total sliding-mode control (ATSMC), high step-up converter, photovoltaic (PV) generation system, pulsewidth-modulation (PWM) inverter.

Trust is important for fostering successful relationships, reducing uncertainty and risk, and increasing willingness to purchase. This study tests the replications in the mobile banking (m-banking) industry and the influence of trust on purchase intention via investigating the relationships between disposition to trust, and trust antecedents to trust in forming trust in m-banking services, which in turn leads to behavioral intention to adopt those services. In spite of numerous studies being focused on the critical role of trust in recent decades, the topic of multidimensional trust antecedents in m-banking, as well as the effects of disposition to trust on m-banking adoption intention has been relatively neglected. Based on the data collected in Taiwan, the results reveal significant positive relationships between disposition to trust, trust antecedents, and trust. Meanwhile, the relationship between trust and behavioral intention are positively significant. Contributions and managerial implications are discussed.

Purpose -The purpose of this study is to develop and empirically test a model examining the relationship between customer perceptions (product attributes, benefits, customer satisfaction, trust, commitment and customer behavioral loyalty) and financial performance of a merchant bank. Design/methodology/approach -Based on the SEM tool of Linear Structure Relation (LISREL), this study develops and empirically tests a model examining the relationships between customer perspectives (product attributes, benefits, customer satisfaction, trust, commitment and customer behavioral loyalty) and the financial perspective (financial performance). A cross-department study in the financial services industry was conducted based on three consumer samples (department of Loans, Deposits, and Credit Cards) drawn from XYZ bank, one of the most famous banks providing merchant banking services in Taiwan. Findings -SEM results indicate that: customer perceptions positively affect financial performance; and customers purchase financial services with dissimilar benefits, all of which come with corresponding attributes, and hence result in different levels of customer satisfaction and behavioral sequence, which is important in reinforcing customers' trust, commitment, repurchase intentions and corporate financial performance. Practical implications -The findings suggest that financial service managers could consider treating consumers as partners in their provision of existing services or their quest to develop successful new services. Reciprocal behavior will foster a positive atmosphere, remove barriers arising from risk, and enable relationships to progress, ultimately improving financial performance. Originality/value -The research proposes an empirical model of the customer perceptions in the consumption of financial services that has a positive impact on the financial performance of the company. The findings are based on data from one company across three product departments.
