A new high voltage gain step-up converter with minimum phase characteristic.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
DC-DC converters are critical components in contemporary power electronics systems, facilitating efficient power conversion and distribution across various applications. Conventional step-up converters typically exhibit a right-half-plane zero in their transfer function, leading to non-minimum phase characteristics. This behavior restricts the stability margin and makes the dynamic response time undesirable. This paper presents a novel topology designed to address the non-minimum phase problem. In this converter, a portion of the energy from the input source is transferred to the output via the coupled inductor. Additionally, the required voltage gain can be attained by utilizing the quantity and positioning of the coupled inductor's secondary windings. The voltage gain, stress voltage on semiconductor devices, and losses are calculated through steady-state analysis. The control signal to the output voltage transfer function is obtained through small signal analysis. The results from the laboratory prototype and simulations in two distinct scenarios are presented to validate the performance and integrity of the mathematical analysis.
