Description: This paper presents the Direct Power Control of
Three-Phase Matrix Converters (DPC-MC) operating as Unified
Power Flow Controllers (UPFC). Since matrix converters allow
direct AC/AC power conversion without intermediate energy
storage link, the resulting UPFC has reduced volume and cost,
together with higher reliability. Theoretical principles of DPCMC
method are established based on an UPFC model, together
with a new direct power control approach based on sliding mode
control techniques. As a result, active and reactive power can be
directly controlled by selection of an appropriate switching state
of matrix converter. This new direct power control approach
associated to matrix converters technology guarantees
decoupled active and reactive power control, zero error
tracking, fast response times and timely control actions.
Simulation results show good performance of the proposed
system.

Description: that monitor certain conditions in different locations and transfer data
through a network to an endpoint called base station. Because WSN nodes are
often deployed outdoors where a direct power outlet may not be available, energy
efficiency becomes a key factor in the design of WSNs. This work proposes an
antenna transmission power optimisation algorithm (TPOA) which dynamically
adjusts the power level of the transmission according to the last received signal
strength indicator (RSSI). The mechanism was implemented and tested on an
XbeeWSNthat uses a modifiedMixed Hop and signalReceived routing for mobile
Wireless Sensor Networks (MHRWSN) protocol. The energy consumption results
have shown that the proposed system can save as much as 76% of power in Tx
operations while maintaining a packet reception rate of above 85%
