“…Moreover, partly isolated TPCs (PITPCs) and fully isolated TPCs (FITPCs) are preferred in applications requiring high voltage regulation ratios [21,22]. One can deduce from [21][22][23][24][25][26][27][28][29][30][31][32] that PITPCs and FITPCs are usually derived from traditional full bridge (FB) or half bridge (HB) topologies, which use a large number of switches as well as a high frequency transformer (HFT). However, use of an HFT along with a large number of switches, increasing the converter size, losses, cost and may make bulky the converter and reduce the overall power density.…”

“…Following the same concept (benefiting from FB and HF converters), the family of FITPCs was derived in [29][30][31][32]. In order to improve the FITPC performance and increase its power transfer capability, it was suggested in [30] to size the converter auxiliary inductance for use in hybrid energy storage systems. In [31], an innovative FITPC was proposed for a hybrid renewable energy system based on an FB converter with the novel winding connection.…”

This study proposed a novel partly isolated three port converter (PITPC) based on a quasi-Z source converter for photovoltaic applications. Compared with the conventional quasi-Z source converter, the proposed DC-DC converter has dual input sources and uses the switched capacitors and coupled inductor techniques, helping the converter to gain a high voltage. To achieve the power flow control, the proposed converter uses only three power switches with low voltage stress and it is developed for hybridising photovoltaic panels, rechargeable batteries and isolated loads. For this purpose, the proposed PITPC can be easily reconfigured into dual-input single-output, single-input dual-output and single-input single-output modes; so it can even operate when the photovoltaic panel fails to provide energy to the load. Moreover, the study thoroughly discusses various converter operating modes and provides explanations and necessary relationships for circuit operations. The study also explains the control strategy as well as the pulse width modulation waveforms for the proposed converter. Simulation results from MATLAB/Simulink examine the proposed topology performance. The experimental results confirm the advantages claimed for the proposed converter; the results also show a well-distributed efficiency curve and a peak of 96.3%.

A new non-isolated high-voltage gain three-port converter for standalone photovoltaic systems is proposed. The magnetic element of this converter is only one coupled inductor. The primary winding of the coupled inductor is shared between battery charger circuit and main converter. Leakage inductance energy of the coupled inductor is either transferred to battery or is regenerated via the passive-clamp circuit. Using switched capacitor and voltage lift techniques, the voltage gain is significantly increased for both low-voltage ports. Single magnetic element, high-voltage gain with reasonable duty cycle, lowvoltage stress on the switches, low winding turn ratio of coupled inductor and high efficiency are the merits of this converter. The operation principles and the steady-state analysis are described for the three modes of: single-input single-output, single-input dual-output and dual-input single-output. To verify the theoretical analysis, a laboratory prototype with 28 V input, 48 V battery voltage and 380 V output voltage is implemented and tested.
