This paper explores passive switched capacitor based RF receiver front ends for spectrum sensing. Wideband spectrum sensors remain the most challenging block in the software defined radio hardware design.The use of passive switched capacitors provides a very low power signal conditioning front end that enables parallel digitization and software control and cognitive capabilities in the digital ...

Switched capacitor based multilevel inverters with boosting capability are emerging as single stage DC–AC conversion in utilizing low voltage DC sources such solar PV and fuel cell. This paper proposes a single-phase hybrid inverter topology on switched that is capable of generating 9-levels along gain 2. The components required to construct the basic module 11 switches, 1 diode 2 capacitors. b...

Conventional switched capacitor converters have an inherent drawback that their efficiency decreases as the output current increases. This inherent drawback is due to a periodical forced charging and discharging operation in the internal switched capacitors accompanied by a large capacitor current. Their efficiency can not be increased by decreasing its internal resistance. As a result, convent...

In present day's energy conveyance frameworks is experiencing serious force quality issues. These force quality issues incorporate high responsive force trouble, music momentums, burden unbalance, unreasonable unbiased current and so forth. A few solutions for these force quality issues are accounted for in the writing. A gathering of controllers together called Custom Power Devices (CPD), whic...

The single-phase-to-ground (SPG) fault at the valve side of converter transformer is one most critical faults threatening operation bipolar half-bridge modular-multilevel-converter-based multi-terminal direct-current (HB-MMC MTDC) systems. Following a valve-side SPG fault, upper-arm submodule (SM) capacitors in faulty may suffer serious overvoltage, and grid-side currents experience no zero-cro...

The change in system voltage and frequency with changing load creates problem in power system stability. For the sake of system stability and reliability, the reactive power compensation is essential for flexible AC transmission system (FACTS). The variation of reactive power causes impact on the generating units, lines, circuit breakers, transformers, relays and isolators. However the reactive...

This article addresses an efficient heuristic-based approach to assign static shunt capacitors along radial distribution networks using the artificial bee colony algorithm. The objective function is adapted to enhance the overall system static voltage stability index and to achieve maximum net yearly savings. Load variations have been considered to optimally scope the fixed and switched capacit...
