A dual switches high step-up DC–DC converter with coupled inductor (CI) and voltage multiplier cell (VMC) is proposed in this paper. The gate pulses of the are synchronized each other. During ON state switches, CIs charged parallel through input power source during OFF they discharged to output series. energy leakage inductances recycled by passive clamp circuit. circuit for one metaloxidesemic...

Here, a soft switched three-level boost converter with high voltage gain is proposed which suitable for step-up applications wide output power range. In this converter, ZVT auxiliary circuit used provides switching in range of independent load variation. Utilizing coupled-inductors one magnetic core removes extra the and conjunction size reduction. Also, secondary tertiary leakage inductances m...

Now-a-days the new family of dc-dc converters based on three state switching cell and voltage multiplier cells. It present a demonstrate of some advantages and limitations of a several topologies were typically use in voltage step-up applications. The operating principle of this family has chosen the boost converter and discussed in detail. The analysis of converter can applicable in uninterrup...

Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–ac inverter. This paper proposes a converter that employs a floating active switch to isolate energy from the PV panel when the ac module is OFF; this particular design protects installers and users fro...

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...
