The utilization of a cuk converter for control of photovoltaic power using Maximum Power Point Tracking (MPPT) control mechanism is presented in this paper. The main aim of the project is to use cuk converter along with a Maximum Power Point Tracking control mechanism. The MPPT is responsible for extracting the maximum possible power from the photovoltaic panel and feeding it to the load via th...

The comparision of bridgeless isolated cuk converter using proportional integral derivative (PID) and neural controller (NC) is presented in this paper. Due to diode bridge rectifier (DBR) conventional converters suffer from high conduction loss. Bridgeless Cuk converter is used to eliminate the issues. bridgeless isolated (BLI) cuk converter is used to withstand high voltage. Compare to Contin...

ABSTRACT: In this paper a bridgeless Cuk rectifier is used for Power factor correction (PFC) for a BLDC motor. Bridgeless Cuk converter has only two semiconductor switches in the current flowing path. During each interval of the switching cycle it result in less conduction losses and an improved thermal management compared to the conventional Cuk PFC rectifier. To achieve almost unity power fac...

One-Cycle Control is a nonlinear control method. The Flow-Graph modeling technique is employed to study the large-signal and small-signal dynamic behavior of One-Cycle Controlled switching converters. Systematic desig? method for One-Cycle Control systems is provided with the Cuk converter as an example. Physical insight is given which explains how OneCycle Control achieves instant control with...

A step-up bridgeless single phase ac-dc power factor correction (PFC) rectifier based on Cuk topology is proposed for high voltage battery charger application. The proposed topology consists of common input stage and parallel output stages. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as clas...

A bridgeless single phase ac-dc rectifier based Cuk derived converter topology fed BLDC motor is proposed to improvepower factor at the AC mains near to the unity with low THD for PFC applications. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as classical Cuk topology. The partial elimination...

A novel human rotavirus strain, CUK-1, containing a G11 type combined with a P[4] type was isolated from a 1-year-old female patient with fever and severe diarrhea at Our Lady of Mercy Hospital in Incheon, South Korea. This CUK-1 strain showed the highest degree of nucleic acid similarity (98.7% and 93%) to G11 Dhaka6 and P[4] RV 5, respectively. This novel combined type of CUK-1 rotavirus stra...
