IET Power Electronics, Volume 14, Issue 15, Page 2441-2451, 25 November 2021., 2021 Abstract In this paper, a non‐isolated coupled‐inductor high step‐down converter with extended duty cycle is proposed, which operates under discontinuous conduction mode. The soft‐switching condition is provided for all the switches and diodes, which results in the reduction of the switching losses, and the losses related to diode reverse recovery ...

Generalised Tapped Inductor Switcher (GTIS) approach to modelling of high‐order converters
IET Power Electronics, Volume 14, Issue 4, Page 775-784, 18 March 2021., 2021 Abstract A generalized modelling technique suited to integrated and high order Pulse‐Width‐Modulation (PWM) topologies is studied and proposed here. Most integrated converters have their switches shared by more than one inductive element. The proposed generalised tapped inductor switcher model takes full account of the properties of the shared switcher

A single phase voltage regulator module (VRM) with stepping inductance for fast transient response [PDF]
, 2007 A single-phase fast transient converter topology with stepping inductance is proposed. The stepping inductance method is implemented by replacing the conventional inductor in a buck converter by two inductors connecting in series.

High-Efficiency NPC Multilevel Converter Using Super-Junction MOSFETs [PDF]
, 2016 Super-junction MOSFETs exhibit low on-state resistances and low switching losses. However, the reverse recovery behavior of their intrinsic diodes and their output capacitance characteristics make their deployment in freewheeling locations challenging ...

A novel soft-switching inverter using resonant inductor freewheeling [PDF]
, 1997 A novel topology of the voltage-source soft-switching inverter for induction motor drives is presented. The key of this topology is to employ two fractional-duty auxiliary switches and one resonant inductor per phase to provide a favorable zero-voltage ...
