چکیده
This paper presents a soft-switching non-isolated interleaved high step-up topology to implement in renewable energy systems. By using low number of power electronic devices and incorporation with the coupled inductors (CIs) built-in transformer (BIT), simultaneously, mixed voltage multiplier cell (VMC), an ultra-large gain can be obtained. In addition, interlevead structure input side causes diminish current ripple. Moreover, automatic sharing is another characteristic proposed converter. The stresses across semiconductors are decreased by increasing turns ratio implemented CIs BIT also reverse recovery losses attenuated which improves efficiency. Furthermore, zero-current-switching (ZCS) condition for diodes achieved at turn off instant, due leakage inductances magnetic means. Also, MOSFETs switched zero-voltage-switching (ZVS) performance adding active clamp. A 600-W experimental prototype 24-V 400-V output switching frequency 100 kHz built tested examine merits

An Interleaved Configuration of Modified KY Converter with High Conversion Ratio for Renewable Energy Applications; Design, Analysis and Implementation
In this paper, a new high efficiency, high step-up, non-isolated, interleaved DC-DC converter for renewable energy applications is presented. In the suggested topology, two modified step-up KY converters are interleaved to obtain a high conversion ratio without the use of coupled inductors. In comparison with the conventional interleaved DC-DC converters such as boost, buck-boost, SEPIC, ZETA a...

This paper presents a novel interleaved converter (NIC) with extra-high voltage gain to process the power of low-voltage renewable-energy generators such as photovoltaic (PV) panel, wind turbine, and fuel cells. The NIC can boost a low input voltage to a much higher voltage level to inject renewable energy to DC bus for grid applications. Since the NIC has two circuit branches in parallel at fr...
متن کاملA Buck-Boost Converter; Design, Analysis and Implementation Suggested for Renewable Energy Systems
This work introduces a new non-isolated buck-boost DC-DC converter. Interleaved configuration of the suggested structure increases the voltage conversion ratio. The voltage rate of the suggested converter can be stepped-up and stepped down for lower values of duty-cycle, which causes to decrease in the conduction losses of the system. The voltage conversion ratio of the recommended structure is...
