Urgent Task

The need to increase the voltage level produced by PV systems becomes an urgent task to be compatible with the requirements of the AC load, but we meet problems in the operation of the step-up converter at a high duty cycle which is not preferred due to the reduction in voltage gain, and also a higher number of turns ratio in the windings inductance coupled adds to the overall losses of the converter. This article proposes an improved DC-DC converter with a lower duty cycle by integrating three tapped-inductors in new topology, which combined quadratic boost converter and tapped-inductor boost converter. The proposed converter achieves a high voltage gain with a lower duty ratio (Gmax = 14.32) and a maximum efficiency of 98.68% is improved compared to the voltage gain and efficiency results of these converters in several recently published references. The analyses are done theoretically and supported with simulation results. A prototype of the proposed converter has been built to experimentally validate the obtained results.

Conduction Mode

The solar photovoltaic (PV) source is preferred to be functioned at low voltages. The practical systems such as grid-tied systems require a high output voltage causing a reduction in conversion efficiency. To handle this problem, this paper presents a new nonisolated boost DC–DC converter with a single switch suitable for solar PV applications. This converter comprises dual voltage multiplier (VM) cells, leakage energy recovery scheme, and coupled inductor (CI) techniques to get the desired output voltage from the converter. The double-clamp capacitors are connected to the primary side of the CI. The clamp capacitors can share the current through CI, and it ensures that the leakage inductance energy of CI can be recovered, leading to an expansion in the converter voltage gain and conversion efficiency. In addition, the clamp circuit clamps the voltage stress of the MOSFET switch, and the clamp capacitors will discharge at a specific time to increase the converter gain. A high duty cycle is not necessary for getting a high voltage gain, which avoids the diode reverse recovery issues. The converter can be operated in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM). A 500-W experimental prototype is developed for experimental validation, and the supporting simulation results are presented. The maximum efficiency of the converter is 93.94%, and, at full load, the efficiency is 92.55%.
