Due to attractive features, including high efficiency, low device stress, and ability boost voltage, a Vienna rectifier is commonly employed as battery charger in an electric vehicle (EV). However, the 6k ± 1 harmonics acside current of deteriorate THD ac current, thus lowering power factor. Therefore, closed-loop for suppressing essential meet desired total harmonic distortion (THD). Fast repe...

Abstract To solve the problem of feature extraction in electronic circuits due to nonstationary and nonlinear characteristics fault signals, a method for is proposed, which combines wavelet packet analysis an improved landmark ISOMAP mapping algorithm. The technology used decompose reconstruct signals at multiple levels. extracted entropy construct vector matrix. density-based spatial clusterin...

The Vienna-type rectifier is broadly employed in various implementations thanks to realizable three-level operation, simple structure and controllable DC-link voltage. This paper proposes an adaptive proportional integral (PI) with anti-windup based direct power control (DPC) improve dynamic response during load change, voltage step change start up reduce current tracking errors. An PI utilized...

In this paper, a linearized time-invariant voltage-sensorless direct power control (DPC) with balanced and unbalanced dc-link voltage is proposed in three-phase Vienna rectifier. To achieve sensorless voltage, the architecture consists of three sub-architectures, including 1) linear control; 2) virtual flux, input active reactive estimators; 3) zero crossing distortion capacitor unbalance compe...

Emission of greenhouse gases and scarcity fossil fuels have put the focus scientific community, industry society on electric vehicle (EV). In order to reduce CO 2 emissions, cutting-edge policies regulations are being imposed worldwide, where use EVs is encouraged. best scenarios reaching 245 mi...
