“…PV technology for electricity generation can either be for grid or off-grid application (Boukenoui et al, 2017). Depending on the purpose it is meant for, they always end up generating less than the demand power, and the quest for higher power generation is the reason why PV panels are connected in series-parallel arrangement (Guangqun and Xuezhi, 2012). And this arrangement is the reason why it requires a very large number of PV panels and wide area for installation (Saravanan and Babu, 2017).…”

This study presents a single switch non-isolated DC-DC converter good for photovoltaic (PV) applications. The proposed topology was constructed using two classical DC-DC boost converters by arranging them in cascade for providing high voltage gain, low duty-cycle, less stress across the semiconductor devices, less size, and low cost. The operating principle and steady-state analysis of an individual component of the proposed topology in continuous conduction mode (CCM) are discussed and the results obtained improved the ones in literatures. The prototype of 120 V DC output voltage with 9 V DC input voltage is implemented and the result obtained validate the simulated result of the proposed converter. Keywords: DC-DC converter, Photovoltaic (PV), Single switch, High gain, Duty-cycle.

“…This converter performs the operation of the zero voltage switching (ZVS) by using a phase shift PWM technique using the leakage inductance of the transformer; thus, a highly efficient system can be developed even at high switching frequencies. Also, the secondary diode can be configured as a switch to enable bidirectional power transfer [5][6][7].…”

This paper examines the characteristics of the zero voltage switching (ZVS) and zero voltage transition (ZVT) soft-switching applied in the 3-phase current fed dual active bridge (3P-CFDAB) converter, which combines the advantages of the dual active bridge (DAB) converter and current-fed full bridge (CFFB) converter. When an active clamp circuit is added to the CFFB converter, the circuit configuration of the DAB converter is shown in part of the entire circuit. This allows the use of pulse width modulation (PWM) techniques which combine the PWM techniques of both the DAB converter and CFFB converter. The proposed converter performs both duty and phase control at the same time in order to reduce the circulating current and ripple current of the output capacitor, which are the disadvantages of the CFFB converter and DAB converter. In addition, the ZVS and ZVT soft switching areas were analyzed by means of the phase current and leakage inductor current in each transformers. To verify the principle and feasibility of the proposed operation techniques, a simulation and experiment were implemented with the 3P-CFDAB.
