Power and Energy

The objective of this research was to propose an insulated gate driver topology for medium voltage application using a single isolated structure. The proposed approach transmits both power and control signal guarantying a reduction of the circuit complexity compared to other solutions.

An inductive power transfer (IPT) system is envisaged as the best solution to conveniently charge electric vehicles (EVs). While stationary IPT systems are becoming commercialized, significant research is being conducted to address the challenges related to dynamic IPT systems. Dynamic or in-motion IPT systems require a fully electrified roadway with embedded inductive couplers with accompanying circuitry. The large number of electronic components required, however, increases the system complexity, reducing the reliability and economic viability of dynamic IPT systems proposed to-date.

This paper proposes a reduced switch count WEtype inverter topology that employs one DC source, nine IGBTs, and one AC-switch comprising of two antiparallel IGBTs, and two capacitors. It is capable of generating 1.5 times boosted 13- level output voltage and employs modified Nearest Level Control (NLC), which considers both zero states. An algorithm based on redundant states controls the voltage across the auxiliary DClink at Vdc/2.

Globally building sector energy consumption is increasing rapidly. Improving building energy efficiency is essential for sustainability. Load monitoring provides detailed consumption feedback to enable consumers to save energy. Non-Intrusive Load Monitoring (NILM) is a cost-effective way to identify individual appliance energy consumption from aggregate energy consumption.
