Generation of circularly polarized (CP) light with high purity and intensity was achieved using a single-, parallel, multi-layered luminescence-based CP convertor composed linearly luminescence (LPL) film quarter-wave plate.

Obiectivul acestei lucrări constă în dezvoltarea şi implementarea unui regulator digital PID pentru convertoarele statice. Sunt studiate prin simulare şi experimentări efectele factorilor KP, KI şi KD asupra răspunsului buclei de reglare. În partea a doua a lucrării, este prezentată o analiză comparativă experimentală a două convertoare (un redresor comandat realizat din tiristoare cu filtru ca...

A new model of Interphase Power Controller (IPC) for controlling active power is introduced in this paper. In this model, which is called VSC-based IPC, the voltage source converter (VSC) does the function of the phase shifting transformer (PST) in IPC. This new structure not only has the features of IPC, but also controls the output power effectively when the input power is changed by alternat...

This paper discusses design, simulation and fabrication of new Micromechanical Thermal Converters (MTCs) based on GaAs developed for Gas sensors. GaAs MTCs seem to be very attractive for design of thermally based MEMS sensor devices. High thermal isolation of these devices can be done by implementing of free micromechanical hot plates which is designed as thin as possible. Metal oxide gas senso...

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connect alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC grid connection of offshore wind farms.

Thermoelectric devices may have an essential role in the development of fuel-saving, environmentallyfriendly, and cost-effective energy sources for power generation based on direct conversion heat into electrical energy. A wide usage thermoelectric systems already exhibits high reliability long operation time space industry gas pipe systems. The application solar generators (TEGs) arelimited ma...

A voltage current convertor is described having a quasi complementary class AB architecture that is particularly suited to implementation using discrete power MOSFETs. High-voltage mirror designs are presented, enabling the construction of sources with kilovolt compliance range, tens of watts of output power and greater than 100 kHz bandwidth. GΩ output impedance and distortion below 1% can be ...
