This paper presents a boost DC-DC converter topology with non - isolated high gain and output midpoint, to boost the voltage obtained from solar photovoltaic panels. The three-level boost converter is coupled to the output port of the single-switch quadratic boost converter to derive the proposed converter topology. The voltage gain of the proposed converter is greater than that of the classical boost converter. The voltage stress on the switches of the proposed converter is equal to half of the converter output voltage. Static analysis, operating modes, experimental waveforms in continuous current conduction and discontinuous current conduction modes are shown. A 520 W prototype converter was implemented in the laboratory and its results are presented.

In this paper, a new transformerless buck–boost converter is introduced. The proposed converter voltage gain is higher that of the conventional buck–boost converter. In the presented converter, only one power switch is used. The switch voltage stress is low, therefore, the low on-state resistance of the power switch can be selected to decrease losses of the switch. The presented converter topology is simple, hence the control of the converter will be simple. The mathematical analyses and principle of the proposed converter are explained. The validity of the proposed converter is confirmed by the experimental results.

This paper presents a new high step-up isolated DC-DC converter topology for photovoltaic system. The suggested configuration provides a converter with high voltage gain and reduced switch stress by using three coupled inductor with two hybrid voltage multiplier cell. The operation of the proposed converter is based on a charging capacitor with a single switch in its structure. A passive clamp circuit composed of capacitors and diodes is employed in the converter structure for lowering the voltage stress on the power switch as well as increasing the voltage gain of the converter. Since the voltage stress is low in the provided topology, a switch with a small ON-state resistance can be used. As a result, the losses are decreased and the efficiency is increased. The design of DC-DC boost converter is also discussed in detail. Simulation of DC-DC converter is performed in MATLAB/Simulink and the result are verified

Converter Topology

A new topology for high step-up nonisolated DC-DC converter for solar PV applications is presented in this paper. The proposed high-voltage gain converter topology has many advantages like low-voltage stress on the switches, high gain with low duty ratio, and a continuous input current. The analytical waveforms of the proposed converter are presented in continuous and discontinuous modes of operation. Voltage stress analysis is conducted. The voltage gain and efficiency of the converter in presence of parasitic elements are also derived. Performance comparison of the proposed high-gain converter topology with the recently reported high-gain converter topologies is presented. Validation of theoretical analysis is done through the test results obtained from the simulation of the proposed converter. For the maximum duty ratio of 80%, the output voltage of 670 V is observed, and the voltage gain obtained is 14. Comparison of theoretical and simulation results is presented which validates the performance of the proposed converter.
