摘要
提出一种采用PAM的变频式软启动器 ,为实现高功率因数、低谐波的软启动器奠定了基础。并且采用同步电路以实现安全切换 ,详细分析和研究了这种软启动器的原理和设计。
A kind of variable frequency soft starter with PAM to achieve high power efficiency and low harmonic is presented. To guarantee safe start, a synchronizing switching strategy is realized by using synchronization circuit.The principle and design of this soft starter are also particularly analyzed and researched. Finally, the experimental waves are given.
