In this paper, KY converter and voltage gain enhanced KY converter are included. A KY converter is a voltage step up converter, it can be considered as a buck converter along with synchronous rectification. In general, a KY converter consists of two MOSFET switches. To obtain higher voltage gain we can adopt different methods. Some of these techniques, advantages and disadvantages of each metho...

The KY Converter, Which is a step up converter, The name given to this converter is first letter of the authors, K.I. Hwu, Y. T. Yau. This converter always operate in CCM, and the output current is non-pulsating, and low output voltage ripple and higher voltage boosting capability. In this paper, different modes of KY Converters are studied. The simulation is carried out to study the perfomance...

Received Nov 21, 2017 Revised Jan 29, 2018 Accepted Feb 17, 2018 This paper presents a performance investigation of bldc motor employing KY converter. Conventional The landsman converter is used to minimize the ripples but the inverter produces high output power ripples, which in turn affect the output of the inverter in The proposed KY converter reduces ripples and smooth dc supply gives to th...

Most mobile equipments use battery as power source. The increasing use of low voltage portable devices and growing requirements of functionalities embedded into such devices. Thus an efficient power management technique is needed for longer battery life for them. Given the highly variable nature of batteries systems often require supply voltages to be both higher and lower than the battery. Thi...

– The demand of the non-isolated voltage-boosting converters has experienced an unprecedented augmentation in the last decade. The diversified application domains host the variety of specifications and rating on DC/DC converters and several variations has been addressed, in addition to the basic buck and boost converters. The main issue with them is presence of objectionable level of voltage ri...

Electric drives are gaining much importance in the present scenario, as the conventional energy sources are at the verge of depletion. The PMDC (Permanent Magnet Direct Current) Motor Drives are becoming popular, for its usage in compact electric vehicles. This paper presents a comparative study of well-known KY converter, its coupled inductor step-up derivative, with the boost converter to acc...
