High-power light-emitting diodes (LEDs) and high-brightness LEDs have revolutionized the
lighting industry. The availability of cost-effective LEDs with high luminous flux, efficacy, and …

Solid-state switch mode AC-DC converters having high-frequency transformer isolation are
developed in buck, boost, and buck-boost configurations with improved power quality in …

A high-power-factor rectifier suitable for universal line base on a modified version of the
single-ended primary inductance converter (SEPIC) is presented in this paper. The voltage …

Unlike existing single-stage AC/DC converters with uncontrolled intermediate bus voltage, a
new single-stage AC/DC converter achieving power factor correction (PFC), intermediate …

This paper proposes a novel single-stage high-power-factor ac/dc converter with
symmetrical topology. The circuit topology is derived from the integration of two buck-boost …

Unlike existing single-stage AC/DC converters with uncontrolled intermediate bus voltage, a
new single-stage AC/DC converter achieving power factor correction (PFC), intermediate …

Quadratic converters have the voltage conversion ratios of two cascaded converters, but
with fewer switches. They are not widely used, however, because they are generally less …

This article introduces a new single-stage universal-input isolated ac–dc converter based on
the impedance control network (ICN) architecture. This resonant converter performs both …

This paper presents a new single-stage single-switch (\rmS^4) high power factor correction
(PFC) ac/dc converter suitable for low-power applications (≪ 150 W) with a universal input …

A buck-boost-type unity power factor rectifier is proposed in this paper. The main advantage
of the proposed rectifier over the conventional buck-boost type is that it can perform input …
