چکیده
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 method are described. It is found that the use of coupled inductor is the better method for voltage gain enhancement. Thus a voltage gain enhanced step up converter constructed by KY converter and buck-boost converter is presented. The two topologies are simulated using Matlab software. It is found that the output voltage is improved when a co obtained.
