Development of Multiple Beam Guns for High Power RF Sources for Accelerators and Colliders

There is a need for high power RF sources for the next generation of accelerators and colliders. Sources that operate at reduced beam voltage allow solid state power supplies with significant cost reduction over conventional pulse modulators. Multiple beam RF sources provide reduced beam voltage by using a multiplicity of beamlets that traverse the RF circuit through individual beam tunnels, re...

Conduction and Dead-Time Voltage Drops Estimation of Asymmetric Cascaded H-Bridge Converters Utilizing Level-Shifted PWM Scheme

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

The Self-excitation Process in Electrical Rotating Machines Operating in Pulsed Power Regime

The self-excitation process in pulsed air-core rotating generators is fundamental in assuring record values of power density and compactness. This paper will analyze the conditions for the self-excitation process in pulsed electrical machines used as power supplies for electromagnetic launchers, using the analogy and methods of the positive feedback in control systems. In the classical “ferroma...

Methods for Estimation of Voltage Harmonic Components

The estimation of harmonic components of power voltage signals is one of the measurements prescribed by the power quality (PQ) standards (IEC 61000-4-30, 2008). In general, the harmonic components originate from non-linear elements connected to the power system such as non-linear loads (e.g., switched-mode power supplies) or transformers. An example of a distorted voltage measured in an office ...

Analysis of Reliability Indices in Next Generation Microgrids Under Uncertainties of Load and Renewable Power Production

In this paper, Multi-Microgrids (MMG) are considered as future smart distribution grids, in which small scale energy resources (SSER) are main power generation units with small scales. Optimal operation of microgrids in defined intervals is carried out to achieve economic conditions in distribution systems. The defined operating problem is optimized using a heuristic algorithm considering uncer...
