摘要
为了满足极限环境对电源系统的要求,本文设计了一种基于SiC器件的高温隔离开关电源。针对光耦反馈的温度局限,本文提出了直接反馈隔离驱动的结构,设计了高温隔离驱动模块,能够对输出电压实现高精度、高效率的控制,并且能够较好地降低温度对反馈精度的影响。测试结果表明所设计的高温直流开关电源系统可以稳定工作在150℃的高温环境中。
In order to fulfill the requirement of power supply under extreme environments,a high-temperature isolating switching power supply system based on SiC device is designed and presented in this paper.Due to the temperature limitation of opticalcoupler,a direct feedback with isolated gate driver approach is proposed to achieve the isolation between the primary and the secondary sides,while maintaining high-precision,high-efficiency control of the output voltage and reducing the influence of temperature on the accuracy of feedback.Fabrication and testing of the prototype system shows that the proposed high temperature DC switching power supply is capable of stable operation in high temperature environment of 150℃.
