By utilizing one coupled inductor and two auxiliary diodes, the bridgeless boost rectifier has a lower conduction loss and no diode reverse recovery problem. Detailed analysis of the novel boost rectifier is presented in this paper. The experimental results of a 300W prototype was analyzed and the excellent performance of the bridgeless boost rectifier was also shown. Dual Boost PFC brings higher...
This paper proposed a co-estimation scheme of State of Charge (SOC), State of Health (SOH), and State of Function (SOF) for lithium-ion batteries. The Extended Kalman Filter is adopted to SOC estimation. Battery parameters are identified online by using Recursive Least Square Algorithm to further estimate battery SOH and SOF. The accuracy of the estimation is improved and the computation is reduced...
Analyzing the performance of satellite photovoltaic (PV) array before launch and in space missions is crucial for energy balance and missions success. This study proposes a specific method to predict the electrical characteristics of body mounted solar array for microsatellite. Based on limit data provided by manufacturers and semiconductor band gap, the equivalent circuit model and its parameters...
