An electronic ballast for multiple tubular fluorescent lamps is presented in this paper. The proposed structure features high power-factor, dimming capability, and soft-switching to the semiconductor devices operated in ...

In medium-voltage applications, the main issue with multilevel converters is that they require a large number of semiconductor switches when higher voltage levels are required. The main objective of this paper is to propose ...

We study the polarization switching of vertical-cavity surface-emitting lasers based on simulations of the spin-flip model. We show that the switching point depends on the ramp signal used to scan the injected current. ...

This work presents a comparative study of semiconductor losses applied to Voltage Source Inverter - VSI for industrial drives applications with different soft-switching techniques. The evaluated techniques are Zero Current ...
