Coupled-inductor rectification and cycloconversion

APEC '88 Third Annual IEEE Applied Power Electronics Conference and Exposition, 1988
AC-to-DC rectifiers and polyphase AC-to-DC cycloconverters are derived from the basic DC-to-DC converters by the addition of negatively coupled inductors with a minimal number of switching devices. The circuits also use space and time-multiplexed magnetics to handle the multiple inputs and outputs.

DC chopper with coupled-inductor commutation

International Journal of Electronics, 1984
A novel coupled-inductor commutation circuit is described. The circuit may also be used for inverters. It uses only two auxiliary thyristors, each operating in alternate cycles and eliminating the need for reversal of the commutating capacitor voltage. Trapped energy is fed back to the source.

Coupled-Inductor L-Source Inverter

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2017
Coupled-inductor L-source inverter is proposed in this paper. Compared to other existing impedance source inverters, the proposed inverter has a unique advantage that makes the proposed inverter flexibly work in two current modes: continuous conduction mode (CCM) and discontinuous conduction mode (DCM).

Automatic tuning of coupled inductor filters

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
A coupled inductor filter is presented with interesting notch mode filtering characteristics. Although this configuration has been long established, it has received little attention. The new contribution of this paper is to provide an automatic tuning process that can make use of the frequency domain characteristics of the coupled inductor building ...

Coupling inductor models for EMI filters

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper analyzes the electrical parameters of differential-mode (DM) and common-mode (CM) inductors used in EMI filters. To design an EMI filter, it is necessary to identify the various parameters of the passive elements: inductors and capacitors. Because of their major impact on filter efficiency, these elements must be identified with accuracy. In

Modeling and design of transformers and coupled inductors

Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002
The modeling and design of transformers and coupled inductors are discussed. After a brief review of Maxwell's laws and magnetic circuit models, the magnetic and electric models of transformers and coupled inductors are developed, including both magnetizing and leakage effects.

Coupled-Inductor Inversion, Rectification and Cycloconversion

1986
A new PWM approach using three state switching of negatively coupled inductors can be applied to any basic dc-to-dc converter to form single-phase dc-to-ac inverters. Current reference programming gives improvements in linearity, small-signal dynamics, and pulsed-load response. The current programming loops of the flyback and boost inverters are stable

Coupled inductor characterization and SPICE modeling

Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990
A complete coupled inductor characterization method, including leakage flux, is described, and its SPICE model is presented. Another SPICE model is developed for p-p ripple current determination in the windings of the coupled inductor in a switching converter and its use is extended to AC stability and audiosusceptibility analyses. >
