Multi-mode controlled push-pull boost power factor corrector

TL;DR: In this article, a push-pull boost PFC topology is proposed to distribute the input and output currents equally in the internal two-phase modules, and coupling the two phase boost inductors into the same magnetic core to allow the reduction of both the circuit volume and the input current ripple under the same inductance.

3-Phase Back to Back Active Power Filter for a Multi-Generator Power System with Reduced dc-link Capacitor

TL;DR: In this paper, a back-to-back active front-end is proposed to improve the drawbacks of the existing shunt-type front end, where PI+R compensator is introduced for the current loop and it effectively eliminates up to 19th harmonic in ac mains.

Adjustable Speed Drive Neutral Voltage a DC Distributed Shift and Gkounding Issues in System

TL;DR: In this paper, a system-level analysis of the voltage ship brought about by both the front-end and secondary converters is presented, where it is shown that the noise caused by the frond-end converter is worse than that from the voltage source inverter itserf, because it will propagate along the dc bus and penetrate to downstream converters.

Dual-Loop Control for Synchronous-Conduction-Mode Tapped-Inductor Buck Converter

TL;DR: In this article, a dual-loop control of a tapped-inductor (TI) buck converter under synchronous conduction mode (SCM) is proposed. But the converter efficiency under SCM is refrained by circulating current and therefore a dualloop (DL) control is proposed in this paper, which is based on a time-domain model for zerovoltage switching (ZVS) process.

A MHz LCLCL Resonant Converter Based Single-Stage Soft-Switching Isolated Inverter With Variable Frequency Modulation

TL;DR: In this paper , a single-stage, soft-switching isolated inverter with variable frequency modulation is proposed, where the paralleled LC within the LCLCL resonant tank can naturally create a zero voltage gain at their resonant frequency, which shows superior characteristics for rectified sine wave generation.
