Publikováno v: IEEE Transactions on Power Electronics. 36:6142-6146

Due to the limit in current-rating of SiC MOSFETs, a number of SiC-based modular ac–dc converters needs to be paralleled to increase power capacity. The number of modular converters ( $N$ ) may vary depending on the customer's requirement. On the o

Reduced Common-Mode Voltage PWM Scheme for Full-SiC Three-Level Uninterruptible Power Supply With Small DC-Link Capacitors

Autor: Jianghui Yu, Sungjae Ohn, Harish Suryanarayana, Rolando Burgos, Dushan Boroyevich

Publikováno v: IEEE Transactions on Power Electronics. 35:8638-8651

In this article, a pulsewidth modulation (PWM) scheme for three-level full-SiC uninterruptible power supplies is developed to achieve a high power density. Two key passive components are selected for size reduction of the ac–ac stage: common-mode (

A Novel Filter Structure to Suppress Circulating Currents Based on the Sequence of Sideband Harmonics for High-Power Interleaved Motor-Drive Systems

Autor: Dushan Boroyevich, Sungjae Ohn, Hyun-Sam Jung, Seung-Ki Sul

Publikováno v: IEEE Transactions on Power Electronics. 35:853-866

In this paper, a novel filter structure to suppress circulating currents is proposed based on the sequence of pulsewidth modulation voltage harmonics for high-power interleaved motor-drive systems. The sideband harmonics can be divided into positive-

Fault Tolerant Operation of Interleaved Converters using a Bypass Switch Arrangement

Autor: Sebastian Nielebock, Sungjae Ohn, Ripun Phukan, Dong Dong, Gopal Mondal, Rolando Burgos

Publikováno v: 2021 IEEE Applied Power Electronics Conference and Exposition (APEC).

The Secondary Loop Filter Building Block (SL-FBB) was proposed as a prospective modular Filter Building Block (FBB) candidate that is scalable and extendible to any number of converters without significant loss in harmonic attenuation. One major adva

An Approach to Localize Circulating Current for Three Phase Interleaved AC-DC Converters

Autor: Rolando Burgos, Dong Dong, Sungjae Ohn, Ripun Phukan

Publikováno v: 2021 IEEE Applied Power Electronics Conference and Exposition (APEC).

Majority of the interleaved converter applications require inter-channel coupled inductors to block circulating currents between converters. Primary advantages being smaller size and weight. However, a standalone filter (i.e. no interconnection betwe

Three-Terminal Common-Mode EMI Model for EMI Generation, Propagation, and Mitigation in a Full-SiC Three-Phase UPS Module

Autor: Christopher Belcastro, Paul Rankin, Dushan Boroyevich, Jianghui Yu, Rolando Burgos, Bingyao Sun, Sungjae Ohn, Harish Suryanarayana

Publikováno v: IEEE Transactions on Power Electronics. 34:8599-8612

With superior loss characteristics, wide bandgap devices such as silicon carbide (SiC) mosfet s are expected to replace Si-IGBTs in grid-connected applications. Uninterruptible power supply (UPS) is an application in which low conduction-loss and swi

Differential-Mode and Common-Mode Coupled Inductors for Parallel Three-Phase AC–DC Converters

Autor: Xuning Zhang, Dushan Boroyevich, Sungjae Ohn, Rolando Burgos

Publikováno v: IEEE Transactions on Power Electronics. 34:2666-2679

In this paper, an integrated structure of coupled inductors is proposed for three-phase ac–dc power conversion. According to the differential-mode and common-mode, three coupled inductors are integrated into two inductors; one for suppressing only
