The MPBC performance is evaluated and compared with other established topologies. The proposed MPBC interfaces two unidirectional input DC power ports and a rechargeable port for an energy storage element (ESE) with two output ports. The design integrates two renewable sources with the ESE as a third source. One output is for higher voltage, linked to a single\u2010phase inverter for AC loads. The other output is for lower DC voltage, used for DC loads. The configuration can be adjusted based on requirements. This converter has numerous applications in renewable energy systems, electric vehicles, and agriculture. The steady\u2010state and small signal modeling of MPBC has been done to derive the mathematical expressions for analyzing stability, stresses (both voltage and current), and performance considering ESRs. A 240\u2009W, MPBC is fabricated along with improved switching strategies using DSP TMS320F28379D. Experimental and simulation results are compared to show the effectiveness of proposed scheme on stability, stresses, and efficient power transfer. Output power is regulated effectively by sharing the input power thereby reducing voltage stress on switches.<\/jats:p>","DOI":"10.1002\/cta.4234","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T02:11:39Z","timestamp":1724292699000},"page":"2602-2633","update-policy":"https:\/\/linproxy.fan.workers.dev:443\/https\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Mathematical
