The purpose of this paper is unavailability of the two main types of conve Swedish traction power supply (TPS) system, i.e. static converter. The number of outages and the ou used to analyze and compare the unavailability o converters. The mean cumulative function (MCF) analyze the number of outages and the unavailab the forced outage rate (FOR) concept has been u outage rates. The study shows ...

With special emphasis in recent years, an increase has been verified not only demand but also the price of electricity, arising need to develop more reliable and efficient electrical energy conversion systems. In this context, emerges utilization modular multilevel converter (MMC) based on submodules. The key MMC is modularity, which allows reach higher performance levels, improving voltage cur...

Multi-stage analog-to-digital converters are the dominant choice in applications that require both high speed and high accuracy, such as video and wideband radio [1]. Non-idealities such as static device mismatch and dynamic timing mismatch, in different architectures of multi-steps analog to digital converter affect the redundancy and performance at the output of an instrument. Redundant sign ...

An on-going extensive research on multi-level and matrix converters requires physically meaningful easy-to-calculate criteria to compare numerous suggested converter topologies and voltage modulation strategies. Frequency domain voltage Total Harmonic Distortion (THD) criterion approach is too complicated and non-transparent as it involves multiple Fourier integral and results in multiple serie...

Abstract In this paper, the dual closed-loop control strategy with fractional-order PI is applied to field of DC-DC converter, which effectively improves dynamic performance and static output voltage power electronic DC chopper converter. The open-loop transfer function Boost converter obtained by modeling analyzing operating principle small-signal model parameters double are combining frequenc...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

We describe a floating-gate trimmed 14-bit 300-MS/s current-steered digital-to-analog converter (DAC) fabricated in 0.25and 0.18m CMOS logic processes. We trim the static integral nonlinearity to 0.3 least significant bits using analog charge stored on floating-gate pFETs. The DAC occupies 0.44 mm of die area, consumes 53 mW at 250 MHz, allows on-chip electrical trimming, and achieves better th...
