摘　　要：随着舰船电气化程度的提高和吨位的增大,舰船电力系统对断路器整定的要求越来越高。根据直流整定电源输出电流的需求,设计了整定电源的硬件拓扑结构,利用新型开关电源替代传统的线性电源,并且对输入整流滤波电路、逆变电路和高频变压器进行结构设计及相关参数的计算。在硬件设计基础上研制了一台整定电源样机。试验结果证明,研制的整定电源硬件拓扑结构合理,电源响应速度较快,而且输出电流具有较高的品质。With the development of electrization and the increase of tonnage in warship, there is more setting need to proteetive switching for warship power system. The topological structure was designed to meet the need of output current of the DC switching setting supply. The new switching power supply was used to displace the traditional linear power supply. The circuit of the input reetifier filter, the inverter and the high frequency transformer was designed and the circuit parameters were calculated. A setting supply prototype was developed based on the hardware design. The experiment results show that the topology of the setting supply is reasonable, the supply has rapid response, and the output current of the supply has high quality.
