Abstract

Single-cell battery power systems are a promising bus architecture for small scientific satellites. However, to bridge the huge voltage gap between a single-cell battery and power bus, bidirectional converters with a high voltage conversion ratio and a large current capability for the low-voltage side are necessary. This article proposes a bidirectional interleaved pulse width modulation (PWM) converter with a high voltage conversion ratio and an automatic current balancing capability. By adding capacitors to conventional interleaved PWM converters, not only are inductor currents automatically balanced without feedback control or current sensors, but also voltage conversion ratios at a given duty cycle can be enhanced. Furthermore, the added capacitors can reduce voltage stresses of switches and charged-discharged energies of inductors, realizing more efficient power conversion and reduced circuit volume in comparison with conventional converters. A 100-W prototype was built for experimental verification, and results demonstrated the fundamental characteristics and efficacy of the proposed converter.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The converter in [71] operates at step-up and step-down at charge and discharge of the battery, respectively.

    “This converter operates at step-up and step-down at charge and discharge of the battery, respectively.”

    From A Comprehensive Review on Small Satellite Microgrids (2022) · cites this paper as [71]

    Section 3.1 (p. 5) defines step-up operation as raising the battery voltage to the bus voltage; it does not associate step-up with charging the battery. The citing sentence reverses the directions: battery discharge supplies the higher-voltage bus through step-up conversion, while charging from the bus requires step-down conversion. (LLM, conf=0.86)

    Checked by a reasoning model — may be wrong.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
