BLAC Drive System for Electro-Magnetic Brake
Mi-Rim Jeon,Kwan-Yuhl Cho,Hag-Wone Kim,Jin-Woo Lee,Hyung-Soo Mok +4 more
- 17 May 2009
TL;DR: In this article, the authors developed a BLAC motor drive system for Electro-Magnetic Brakes (EMB), which consists of a power converter system which drives a motor and a digital control system which controls the speed, and suggest a vector control strategy for a fast torque response.

Hybrid Current Mode Control for Phase-Shift Full-Bridge Converter
Jae Hak Ko,Seung-Woo Baek,Hag-Won Kim,Kwan-Yuhl Cho +3 more
- 01 Nov 2019
TL;DR: In this paper, a hybrid current mode control that combines both peak and valley current modes was proposed for phase shift full-bridge (PSFB) converters, while considering the magnetizing current and ineffective duty.

Mathematical Analysis of LLC Series Resonant Converter with Current Doubler Rectifier using Coupled Inductor
Jung-Yoon Shin,Soon-Sang Hwang,Byung-Chul Yoon,Hag-Wone Kim,Kwan-Yuhl Cho +4 more
- 20 Oct 2014
TL;DR: In this article, the authors proposed an LLC series resonant converter with a current doubler using a coupled inductor as a rectification circuit for the secondary side, which is not affected by the resonant characteristic of the primary LLC.

Switch Open Fault Detection and Tolerant Operation Method for Three Phase PWM Rectifier
Hee-Keun Shin,Byoung-Woong An,Hag-Wone Kim,Kwan-Yuhl Cho,Shin-Myung Jung +4 more
- 20 Jun 2012
TL;DR: In this paper, the authors proposed a new open fault detection and tolerant operation method for 3-phase PWM rectifier, where the open fault is detected by a simple MRAS (Model Reference Adaptive System) without additional hardware sensors, and the tolerant operation carried out by turning on the opposite switch of the faulty switch without any redundancy.
