摘　　要：因船用电子产品使用环境的特殊性,船用放电装置需满足电磁兼容、散热、噪声等严苛的指标。文章分析放电装置Buck电路和放电电阻的特性,在结构设计上将放电装置的Buck电路和放电电阻进行电磁隔离和热隔离,从而可分别对2部分进行电磁兼容设计和热设计。通过热仿真和试验验证,成功使放电装置满足相关试验指标,并总结出船用放电装置的设计方法。Due to the particularity of marine electronic products,the marine discharge device should meet the strict requirements of electromagnetic compatibility,heat dissipation and noise test.The characteristics of the buck circuit and the discharge resistance of the discharge device are analyzed.In the structural design,the buck circuit and the discharge resistance of the discharge device are electromagnetically and thermally isolated,so that the electromagnetic compatibility design and thermal design of the two parts can be carried out respectively.Through the thermal simulation and test verification,the discharge device meets the relevant test indexes successfully,and the design of the marine discharge device is summarized method.
