helpful to reduce the conduction losses by using low power rated components and efficiency will increase. Single switch is used in the non-isolated high step up converter, thus reduce the entire cost of the converter. The energy stored in leakage inductance of coupled inductor is efficiently recycled to the output. The voltage doubler circuit is added for further extending the voltage gain. The control strategy is the one cycle control. By the application

SINGLE STAGE POWER FACTOR CORRECTION AC-DC CONVERTER Gokul P H Mar Baselios College of Engineering Mar Ivanios Vidya Nagar, Nalanchira Email id: Sojy Rajan Assisstant Professor Mar Baselios College of Engineering Mar Ivanios Vidya Nagar, Nalanchira Email id: Abstract— A novel single-stage high-power factor ac to dc converter with symmetrical topology which is compared with traditional full bridge series parallel resonant converter. Traditionally, an ac/dc converter consists of a diode-bridge

different sources. The Full bridge TPC can be used across a wide source voltage range, and good control over two of the three ports can be achieved while the third port provides the power balance in the system. Moreover, the energy stored in the leakage inductance of the transformer can be utilized to achieve zero-voltage switching for all the primary-side switches. Experimental results verify the feasibility and effectiveness of the developed Full Bridge-TPC. Index Terms—FB-TPC, dc grid, full-bridge three-level

operation of the SRM complicates the analysis as well as the control of the motor [1-5]. Based on the modelling of SRM magnetic circuit, three models of SRM are found in literature: linear model, nonlinear model without mutual inductances, and nonlinear model with mutual inductances. Linear models in [6,7] are designed and simulated readily. On contrast nonlinear models are obtained after a large set of experimental tests to obtain the magnetic characteristics [8-15], or from a finite element method (FEM)

There may be a possibility of high levels of harmonic voltage and current distortion. • Line transients can cause damage to the VFDs. • AFD impedance requirement may not be met. DC Choke On the front end of the adjustable frequency drive, a series inductance on the DC side of the semiconductor bridge circuit is called a DC choke. An equivalent AC-side line reactor is comparable to the DC choke, except that the THD of DC choke is less than that of the AC counterpart. A greater reduction of the 5th and

The line inductance X lags the current Ip creating a voltage drop in the line inductance and VCOMP will generate a voltage in opposite direction in order to reduce voltage drop across the line inductance. Series compensation capacitor is connected in series in the transmission line as shown in Figure B: It means that all the equipment must be installed
