The aim of this research is to present a simple online condition monitoring system to predict failure of the aluminum electrolytic capacitors used in the output LC filter of the switched mode DC–DC buck converters. Equivalent Series Resistance (ESR) is the best indicator of the failure of the aluminium electrolytic capacitors. The main idea of the proposed method is to monitor the ESR value and...

This paper presents a new single stage DC-DC multilevel boost converter topology with very high voltage gain ratio. It is a Pulse width modulation (PWM) based switched inductor multilevel boost converter (SIMLC) consisting of two switched inductors, 2N+2 Diodes, 2N-1 Capacitors for N level boost converter. High switching frequency has been used to decrease component size. The proposed converter...

Presented in this paper is a low power, area efficient reconfigurable analog-to-digital (ADC) converter, utilising a charge-summation technique with a switched-capacitor implementation. Using a non-inverting switched-capacitor integrator a staircase ramp is produced using switching capacitors and a fixed reference voltage, as opposed to a linear ramp. The advantage of the charge summation techn...

-This paper describes an alternative STATic synchronous COMpensator (STATCOM), by connecting a number of Gate Turn Off (GTO) thyristor converters in series on the ac side of the system. Each GTO converter forms one ‘link’ of a 1-phase, full-bridge Voltage-Source-Converter (VSC) and is referred to as a ‘Chain Link Converter’ (CLC). Each GTO of a CLS, is switched ‘ON/OFF’ only once per cycle of t...

One of the most important methods in loss reduction and controlling the voltages of distribution systems is the utilization of the fixed and switched capacitors. To do this, real modelling of the system in actual operational conditions including unbalanced or balanced loading and for actual feeder structure, ie, radial/meshed configuration, are required. In this paper, a new technique for findi...

One of the most important methods in loss reduction and controlling the voltages of distribution systems is the utilization of the fixed and switched capacitors. To do this, real modeling of the system in large scale unbalanced or balanced for both radial and meshed configurations are required. In this paper, a new technique for finding the optimal values of the fixed and switched capacitors in...

This paper presents a predictable fixed gain instrumentation amplifier using switched capacitor instead of resistor to improve the accuracy of the gain as 10. This instrumentation amplifier builds up by two operational amplifiers which connect by switched capacitor. These switched capacitors are used to stable the whole circuit, fix the gain of total instrumentation amplifier. Using two operati...
