An Enhanced Frequency-Fixed All-Pass Filter PLL for Single-Phase Application

Autor: Weidong Xiao, Yuezhu Lu, Samir Gautam, Dylan Dah-Chuan Lu, Saad Ul Hasan

Publikováno v: 2021 31st Australasian Universities Power Engineering Conference (AUPEC).

All-pass filter (APF) offers a simpler implementation for orthogonal signal generation (OSG) and has widely featured in single-phase phase locked loop (PLL) applications. However, they have two prominent issues, the absence of filtering capability an

Quasi-Z-source based bidirectional DC-DC converter and its control strategy

Autor: Saad Ul Hasan, Yuba Raj Kafle, Graham Town

Publikováno v: Chinese Journal of Electrical Engineering. 5:1-9

This paper presents a quasi-Z-source based isolated bidirectional DC-DC converter (qZIBDC) for renewable energy applications. The converter utilizes a dual active bridge circuit with a quasi-Z-source network on both sides, so the converter works as b
