Definition of Apparent Power in 3-Phase 4-Wire Non-Sinusoidal Power Systems
The thesis starts by collating and comparing most power theories in the instantaneous and average power domain. The instantaneous theories are reformulated and classified into three groups, which can be linked with one equation. Introducing a new instantaneous theory based on vector space allows …

Evaluation of Active Capacitor Banks for Floating H-bridge Power Modules
The DC-side floating capacitors in the floating power modules of power converters are subject to high voltage fluctuation, due to the presence of reactive harmonic components. Utilizing passive capacitors, as done in traditional methods, helps reduce the DC-bus voltage ripple but makes the system …

Bi-directional DC-DC converter for low power applications
Applications that require exchange of power from the source to the load and vice-versa have conventionally been implemented with two uni-directional converters; each processing the power in one direction. With growing emphasis on compact, smaller and efficient power systems there is increasing …

Modeling and Simulation of a Cascaded Three-Level Converter-Based SSSC
… clearly the most feasible topology for use as a power converter in the SSSC applications. The control for the CMC-Based SSSC is complicated. The design of the complicated control strategy was begun with well-defined system transfer functions. The stability of the system was achieved by trial and …

Analysis and techniques for non-intrusive appliance load monitoring.
The increased public awareness of energy conservation and the demand for smart metering system have created interests in home energy monitoring. Load disaggregation using a single sensing point is considered a cost-effective way to sense individual appliance operation as opposed to using dedicated …
