Adaptive Linear Combiner로 구성된 Phase Locked Loop 시스템의 특성분석
Performance Analysis of Phase-Locked Loop system composed of Adaptive Linear Combiner
초록
A typical method to control the single-phase power converter system is to utilize the zero-crossing PLL. However, this method is vulnerable to the voltage disturbance and affects the performance of controller. This paper proposes a new single-phase PLL system that is composed of the adaptive linear combiner and the PI control. The operational principle was analyzed through theoretical approach and the performance was verified through simulations with MATLAB. The proposed PLL system shows rapidness and robustness in control under the voltage disturbances such as the sag, harmonics, and phase jump.
