Abstract

In this paper, a single-phase single-stage isolated zero current switched (ZCS) current-fed full-bridge ac/dc converter is proposed for IGBT-based high-power power factor correction (PFC) applications. By adding an additional commutation path and few resonant components, ZCS operation is realized for all IGBTs. The conduction loss is also lowered by the additional path. Furthermore, the control strategy for the proposed converter is compatible with that developed for traditional PFC converter. In this paper, the topology derivation and circuit operational analysis are given. The control strategy is introduced. A 3-kw prototype is developed and tested to verify the circuit functionality. Finally, the efficiency performance is investigated and comparison is made to show the advantages of the topology.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The study in [104] resulted in a zero-current setting, and hence an enhanced converter efficiency of almost 94% with no need for a DC-link capacitor.

    “This study resulted in a zero-current setting, and hence an enhanced converter efficiency of almost 94% with no need for a DC-link capacitor.”
  • The research in [104] suggests a modified version of a full bridge by installing a new path for the current to flow parallel to the full bridge.

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.
