In this paper, a novel single-stage softswitching current-fed full-bridge AC/DC converter is proposed. By adding an additional commutation path, softswitching can be realized for all power devices. The power density is also enhanced by eliminating the DC capacitor. Meanwhile, the conduction loss is also lowered through the use of the additional commutation path. Furthermore, the control strategy for...
The energy consumed by topology maintenance could be higher than that in the initialization stage and the cost will increase steadily with the turns of maintenance process. Therefore, when design a self-organization protocol for WSN, not only initialization cost should be considered but also the maintenance cost in the whole lifetime. Moreover, to reduce the footprint on system resource, the maintenance...
