LCL-T Resonant Converter Based on Dual Active Bridge Topology in Solar Energy Applications
摘要： Resonant LCL-T converter can operate as stable voltage source, being fed from current, for instance, the photovoltaic battery. It is shown that LCL-T resonant tank has intrinsic ability to convert stable AC current into stable AC voltage thus parametrically regulating output voltage at a fixed value. This mode of operation is made possible by the use of active (synchronous) rectifier to recoup energy from the output back to the LCL-T resonant tank. Basic characteristics of resonant LCL-T converter regulated by phase shift between inverter and rectifier regardless of a solar battery current drift have been defined. It is shown that phase control guarantees 0 voltage and 0 current on switching; however, turn-off current could be substantial. Calculations and assumptions made in this study have been confirmed by simulation and hardware prototype.

Optimal planning of distributed photovoltaic generation for the traction power supply system of high-speed railway
摘要： The ever-increasing electricity price and energy consumption in high-speed railway industry push railway companies to seek a promising way to realize their sustainable developments. Making full use of the solar resource along with high-speed railways can be a potential solution to cut the electricity bill, bring more profit to railway companies and realize the decarbonization of high-speed railway industry. This paper studies the optimal planning of distributed photovoltaic generation (DPVG) and energy storage system (ESS) for the traction power supply system (TPSS) of high-speed railway. A quantitative method is proposed to study the time and space characteristics of photovoltaic generation and electricity demand of high-speed trains. An integrated cost-benefit analysis framework is developed to evaluate the effect of DPVG and ESS on the economy of TPSS. To derive the optimal planning scheme and energy management strategy of DPVG and ESS, a mathematical programming model with the objective of minimizing the total cost is proposed to seek the most economical solution. A hybrid global optimal solution approach is developed to solve the model. A real-world case of Beijing-Baoding high-speed railway in China is used to illustrate the capability and characteristics of the proposed model. The computational results show that DPVG is able to supply 48.5% electricity demand of high-speed trains. The integration of DPVG and ESS can help railway company save 4.5 billion CNY each year in Beijing-Baoding high-speed railway. This paper demonstrates the potential and applicability of DPVG and ESS in high-speed railway industry.

摘要： The article presents a selection procedure for the components selection of a bidirectional DC-DC. The converter is used to implement energy storage system as part of a photovoltaic power supply system. The storage system provides energy balance and smooth voltage oscillations in the power supply system’s DC link via controlling energy flows. The considered approach can be used in photovoltaic and electric vehicles and electric drives applications. The paper includes a description of power components selection based on physical properties and power supply system requirements. Besides, an economic analysis of components as a part of power supply system is considered.

[IEEE 2018 International Russian Automation Conference (RusAutoCon) - Sochi, Russia (2018.9.9-2018.9.16)] 2018 International Russian Automation Conference (RusAutoCon) - Reliability Prediction of Radio Frequency Identification Passive Tags Power Supply Systems Based on A<inf>3</inf>B<inf>5</inf> Resonant-Tunneling Diodes
摘要： The methodology of predicting radio frequency identification (RFID) passive tag power supply system reliability is developed. The reliability of a RFID passive tag power supply system is estimated in terms of a parametric failure associated with the I-V characteristics drift of resonant-tunneling diodes (RTD) that are a part of the tag rectifier under the influence of external factors beyond the tolerance limits. The methodology of the time to failure of the RFID passive tag power supply system calculation by the criterion of the minimum permissible range is presented. The developed methodology can be used in the design of RFID systems with passive UHF and SHF tags to predict their reliability under specified operating conditions. The developed algorithms and software modules can be integrated into the corresponding CAD systems.
