This paper investigates the high-frequency discharging characteristics for the lithium iron phosphate battery. The investigation focuses on the effect of the high-frequency current on the dischargeable capacity of the battery. Included are the current profiles of triangle, saw-tooth, and trapezoidal waves, which are produced from commonly used DC-DC(More)
This paper proposes a three-port dc-to-dc power conversion circuit for small-scale distributed generation systems. With the three-port converter, the load can be powered from two different dc sources, which can be a combination of two from a solar-cell panel, a fuel-cell set, a battery bank, etc. The power conversion circuit consists of two active power(More)
