In this paper, a comparative performance of a newly proposed standalone solar PV (Photo-Voltaic) power generating system is presented along with a conventional PV generating system. The new PV generating system is using isolated dc-dc Cuk converter which consists of a high frequency transformer and a conventional PV system consists of a line frequency transformer. Both these configurations are compared...
This paper shows how a seven level MLI can be implemented using lower number of switches using gate drive circuits built with low cost gate drive ICs such as IR2110 family. The technique uses a single dc power supply to feed all the gate drives of an inverter. This type of implementation reduces the total cost of implementation of seven-level MLI and size of driver circuits. Another important feature...
This paper presents an analytical direct gate tunneling current model of recessed-source/drain(Re-S/D) SOI MOSFET. The gate tunneling current behavior has been analyzed by varying different parameters like gate insulator thickness and drain to source voltage. The gate tunneling current has been investigated with the effect of high-k dielectric constant. 2D ATLAS tool has been used to validate the...
Using 6.5 kV Silicon (Si) IGBTs, high voltage high power DC to DC converters are realized either by multi-level converters or series connected devices based two level converters or modular multi-level converter using series connected devices two level converter as building blocks. The introduction of high voltage SiC devices (10 kV to 20 kV) reduces the component count significantly while improving...
