Recent Research from National University Highlight Findings in Electrical Engineering

February 12, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Researchers detail new data in Electrical Engineering. According to news reporting out of Tabriz, Iran, by VerticalNews editors, research stated, "In this paper an Improved Zero Voltage Zero Current Pulse Width Modulation Forward converter which employs a simple resonance snubber circuit is introduced. A simple snubber circuit consists of a capacitor, an inductor and two diodes."

Our news journalists obtained a quote from the research from National University, "In proposed converter, switch Q1 operates at ZCS turn-on, and ZVS turn-off conditions and all-passive semiconductor devices operate at ZVZCS turn-on and turn-off state. The proposed converter is analyzed and various operating modes of the ZVZCS-PWM forward converter are discussed."

According to the news editors, the research concluded: "Analysis and design considerations are presented and the prototype experimental results of a 100w (40 V/2.5A) proposed converter operating at 30 KHz switching frequency confirm the validity of theoretical analysis."

For more information on this research see: Analysis, Design and Implementation of an Improved ZVZCS-PWM Forward converter. Journal of Electrical Engineering & Technology, 2014;9(1):197-204. Journal of Electrical Engineering & Technology can be contacted at: Korean Inst Electr Eng, 901 Kstc, 635-4 Yeoksam-Dong, Gangnam-Gu, Seoul, 135-703, South Korea.
