This article presents a brushless DC motor (BLDCM) drive for maritime electric vehicle (MEV) application. The presented BLDCM uses bridgeless Cuk-buckboost (BL-Cuk-BB) converter input-side power factor (PF) improvement. BL-Cuk-BB the buckboost negative half-cycles of input AC voltages and Cuk positive half-cycles. In case MEVs, systems are generally fed by diesel engine generators (DEGs). asymm...

PV Module Maximum Power Point Tracker (MPPT) is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply. Every photovoltaic (PV) array has an optimum operating point, called the maximum power point, which varies depending on cell temperature, the insulation level and array voltage. The function of MPPT is needed to operate the PV array at its maximum power ...

-In this a new bridgeless isolated power factor correction (PFC)-based Cuk converter-fed brushless dc (BLDC) motor drive is introduced for power factor correction and reduction in total harmonic distortion of input current. Dc link voltage of the voltage source inverter (VSI) feeding the BLDC motor is varied for speed control. This allows the operation of VSI in fundamental frequency switching ...

Power Factor Preregulators (PFP) have been used to improve input current waveform of off-line power supplies. There are two major approaches in implementing control circuits in PFP: the multiplier approach and the voltage-follower approach. The simplest one is the voltage-follower approach because the converter operates in discontinuous conduction mode (DCM), and only one loop control is requir...

This paper is based on the bridgeless single-phase Ac– Dc Power Factor Correction (PFC) converters with Fuzzy Logic Controller. High frequency isolated Cuk converters are used as a modular dc-dc converter in Discontinuous Conduction Mode (DCM) of operation of Power Factor Correction. The aim of this paper is to simplify the program complexity of the controller by reducing the number of fuzzy se...

The widely used converter models in most of the power electronics and power system applications are the DC-DC converter models. Increase in switching losses has been observed in Conventional Diode Bridge Rectifier (DBR) and hence the researchers are more focused towards bridgeless converters. The design of a novel bridgeless cuk converter model with buck mode operation is focused in this work. ...

This experimental study deals with the investigation of chaos during the regulation of output voltage of solar photovoltaic module. The Cuk converter is used as an interface between solar PV module and load, since the Cuk converter is the good choice for the maximum power point tracking (MPPT) circuits. The input voltage of the converter is controlled in order to regulate the operating point of...

We investigate learning dependency grammar from positive data, in Gold's identification in the limit model. Examples are dependency trees. For this, we introduce reversible lexical dependency grammars which generate a significant class of languages. We have demonstrated that reversible dependency languages are learnable. We provide a-time, in the example size, algorithm. Our objective is to con...

This paper deals with the design of a Cuk DC-DC converter for a BLDC drive. A three-phase voltage source inverter is used as an electronic commutator to operate PMBLDCM used in a fan. It uses the concept of the voltage control at dc link proportional to the desired speed of the PMBLDCM. The speed of the motor is controlled to have the optimum speed of the fan and also to improve the power facto...
