A comparison between two-phase and three-phase interlaced DC converter with parallel MOSFET is presented. PWM is evaluated using a two-way DC-DC converter to charge and discharge a battery. The results show an excellent DC voltage gain without an extremely high cycle load. The interlaced DC-DC converters with MOSFETs in parallel in two and three phases offer distinct advantages and limitations. The two-phase converter has a simpler design and a potentially lower cost due to the reduced number of components. However, it can present challenges in terms of precise voltage regulation and current balancing, due to the limited number of switching phases. On the other hand, the three-phase converter offers more precise voltage regulation and improved current balance thanks to its higher number of phases. While this results in increased design complexity and potentially higher cost, it allows for a more uniform distribution of current load among MOSFETs. The choice between the two will depend on the specific requirements of the application, acceptable trade-offs in terms of complexity, cost and performance, as well as the need for accurate voltage regulation and optimal current balancing.INDEX TERMS : battery storage, buck-boost DC-DC converter, interleaved bidirectional DC-DC converter, parallel-connected MOSFET, SOC.

A new high efficiency interleaved pulse‐width modulation (HE‐IPWM) method using parallel‐connected Mosfets is presented. The IPWM is evaluated using a bidirectional DC‐DC converter for charging and discharging a battery. The results show an excellent DC voltage gain without an extremely large duty cycle. Compared with conventional pulse‐width modulation (CPWM), the IPWM reduces by half the ripple of the battery current. The current ripple of IPWM is four times higher of the switching frequency, while CPWM is two times higher. The proposed interleaved strategy also double the inductor current ripple frequency, whereas in general, is equal to the switching frequency. As a result, the use of the IPWM reduces the weight and size of inductor design. Furthermore, IPWM provides the best battery current ripple at the duty cycle close to 25%. The operating stage, mathematical analyses, and design guidelines of the two proposed modulations are explained in detail. The IPWM experimental results of a 250‐W prototype confirmed the circuit performance. The maximum efficiency of 98.9% is obtained at 250 W for boost mode and 99% for buck mode.

SummaryRecent research has focused on high‐power two‐stage photovoltaic (PV) systems, particularly with the introduction of wideband gap silicon carbide (SiC) devices. A massive inductor or interleaved boost converter is utilized in a standard two‐stage system, requiring a significantly larger number of components and subsequently impacting power density. As a result, the purpose of this research is to provide a topology for a high‐power non‐isolated switched capacitor network‐integrated boost converter (SCNIBC). This architecture employs two of every switch/diode/inductor and capacitor. The suggested architecture has a triple voltage boost at 50% duty ratio, excellent efficiency, and very low inrush current. A suitable analysis is performed to determine the voltage gain, component selection, and power loss analysis. Reliability analysis is studied as per the IEC 61709‐2017 standards. A fair comparison with existing state‐of‐the‐art high‐power PV system topologies is offered. Eventually, the steady‐state experimental findings for a 2.5 kW load are confirmed. The results are also validated for a step adjustment in input voltage from 80 V to 96 V. Lastly, the grid connected operation of converter is studied with a H‐bridge inverter under unity, lagging and leading power factors.
