In this paper, a new step-up/step-down AC-AC converter is designed by switched capacitor (SC) techniques. The main features of the proposed SC AC-AC converter are the symmetrical converter topology and the absence of magnetic elements. Owing to the symmetrical converter topology, the number of capacitors in the proposed AC-AC converter is fewer than that in the conventional SC AC-AC converter. ...

Was concentrated on tree phase matrix converter topology. Single-phase Matrix converter or SPMC was first implemented by Zuckerbeger4. Now presented a.Abstract. This paper presents the single phase matrix converter topology that will operate as an uninterruptible power supply circuit. A single circuit is developed.Single phase matrix converter SPMC performs a function such as frequency changer,...

A manufacturing study of a 0.372 THz 8-fold (8F) helically corrugated interaction region (HCIR) and measurement its wave dispersion characteristics are reported. This demonstrates the structure’s suitability as electron beam / electromagnetic in high power frequency tunable Gyroresonant source. The 8F HCIR has an eigenmode, which is ideal for broadband tuning, created by coupling TE <sub xmlns:...

Gallium arsenide (GaAs) based microaccelerometers are being developed for guidance and navigation subsystems, and various microsensor systems. The microaccelerometer is a microelectromechanical system (MEMS) micromachined on top of GaAs substrate or GaAs integrated cirwits. The MEMS accelerometer is integrated on the same chip as the GaAs readout circuit and the GaAs analog to digital converter...

In this paper, we propose two novel memoryless reverse converters for the moduli set {2 − 1, 2, 2 − 1}. The first proposed converter does not entirely cover the dynamic range while the second proposed converter covers the entire dynamic range. First, we simplify the Chinese Remainder Theorem in order to obtain a reverse converter that utilizes mod-(2 − 1) operation. Second, we further reduce th...
