A practical approach to switching-loss reduction in a large-capacity static VAr compensator based on voltage-source inverters [PDF]
This paper presents a simple method for reduction of switching and snubbing losses in a large-capacity static VAr compensator (SVC) consisting of multiple three-phase voltage-source square-wave inverters.

The effect of switching transitions on switched capacitor converters losses [PDF]
The contribution of the rise and fall times of switches to the losses of Switched Capacitors Converters was evaluated by an approximate analysis applying the equivalent resistance concept. It was found that switch turn-on and turn-off durations increase the equivalent resistance of the converter and, consequently, the losses, except in the case of ...

Stolen Artwork: Deciding Ownership Is No Pretty Picture [PDF]
This thesis analyzes the power losses in induction machines and how the losses depend on the harmonic content of the applied voltages. Two cases are compared, one case where a machine is fed with a sinusoidial voltage and one case with a modular ...
