Abstract: This paper studies the reason of Surge test fail caused by the improper layout of PCB,proposes a method to improve the performance of variable frequency circuit to resist Surge interference and solve the problem by adjusting the ground trace and decoupling capacitance of PCB of variable frequency circuit。

Key words: Variable frequency refrigerator, Surge, Ground trace, Decoupling capacitance, EMC, EMS
