A general PWM method for soft-switching three-phase power converters-Edge Aligned PWM (EA-PWM) is proposed. It aligns all the high loss commutation instants of the converter bridges in a switching cycle at the same instant so that all the switches of the

Pulse forming in an AM mode-locking hybrid TEA-CO2 laser [PDF]
We performed an experimental study on the pulse forming mechanism in an AM mode-locked hybrid TEA-CO2 laser by means of “injection mode-locking”. The results show that bandwidth limited pulses will only be reached within a small - critical - range of ...

Passive Mode-Locking of Monolithic InGaAs/AlGaAs Double Quantum Well Lasers at 42GHz Repetition Rate [PDF]
Pulse trains with a 42GHz repetition rate were generated by monolithic InGaAs/AlGaAs double quantum well lasers at a wavelength of 985 [angstroms]. The cavity was electrically divided into three regions, one providing gain and the other two providing ...
