摘要
阐述单相功率变换器的电网同步技术,包括四类单相锁相环技术,锁相环的工作原理、传递函数、工作特性、对系统的抗干扰能力、动态响应特性,运用Matlab仿真模拟,对比在添加谐波前后各类锁相环的锁相效果。
This paper describes the grid synchronization technology of single-phase power converter, including four types of single-phase phase-locked loop technology, the working principle, transfer function, operating characteristics, anti-interference ability to the system, and dynamic response characteristics of the phase-locked loop. Matlab simulation is used to compare the phaselocked effects of various phase-locked loops before and after adding harmonics.
