Can coupled inductor based four port topology multiport converter integrate multiple PV sources?

This article is one among the kind, which proposes a novel Coupled Inductor based Four Port topology Multiport Converter (CI-FP-MPC) for integrating multiple PV sources with different voltages. The adoption of coupled inductor contributes an increased voltage gain with reduced stress on the switches and diodes.

How much power do coupled inductors dissipate?

Comparing with line inductors, coupled inductors dissipate less power in the range of 2.8 Watts. It is to be noted that, even though the rated power is 750 Watts, the power loss calculation is estimated until 1000 Watts.

Why do we use coupled inductor?

It is observed that most of the existing topologies have initiated the usage of coupled inductor as it provides good improvement in reduced stress and increased voltage gain. Another added advantage is the converter is operating in reduced switching frequency, which means the stress on the switches and diodes during commutation is highly reduced.

Is coupled inductor better than existing MPC?

The proposed converter is compared with existing MPC’s on various parameters as contrasted in Table 2. It is observed that most of the existing topologies have initiated the usage of coupled inductor as it provides good improvement in reduced stress and increased voltage gain.

Why is coupled inductor a good choice for a four-port topology?

The adoption of coupled inductor contributes an increased voltage gain with reduced stress on the switches and diodes. In addition, reduced number of switches and diodes for a four-port topology provides an increase in efficiency due to its reduced switching and conduction losses.

Why is coupled inductor used in CI-FP-MPC?

In the developed CI-FP-MPC, the coupled inductor used is to enhance the load current capability when it is integrated with solar panels, however, the size of the coupled inductor and the EMI caused has to be considered as the future scope of this research.
