The ability to understand phenomena in environmental systems is reliant on the ability to measure data about the system. In this realm, a high degree of non-homogeneity can exist between adjacent measurement points. The barrier to increased spatial sampling is device cost. Newer low-cost sampling platforms enable increased spatial sampling allowing for a better understanding of phenomena. Many sensing...
Global time synchronization is an important function that enables all devices in a network to have a unified time. In traditional wireless ad hoc networks, since the spectrum is always available, the global time synchronization process usually can be performed without any interruption. However, in cognitive radio (CR) ad hoc networks, the global time synchronization process among secondary users may...
This paper presents an open-loop synchronized-OFF voltage-mode Master-made-modulated (SFVM-M ) control scheme for a two-phase interleaved boost converter with Master–Slave strategy for power factor correction applications. Interleaving the continuous-conduction-mode and discontinuous-conduction-mode (CCM/DCM) boundary-mode boost converters, however, is complicated because of the variable-frequencies...
This paper presents an open-loop synchronized-off voltage mode (SFVM) control scheme for a two-phase interleaved boost converter with master-slave strategy for PFC applications. Interleaving CCM/DCM boundary mode boost converters, however, is complicated because of the variable-frequencies nature of the operation. The problem of current divergence is often encountered in the Slave converter. In this...
