摘要
分析医用开关电源的工作方式,采用PWM工作方式的连续可调高频开关电源电路,选择PWM控制芯片,设计医用开关电源的主电路。为了验证该方案电路设计的合理性,建立开关电源仿真试验平台,结果表明方案电路设计合理,能够到达预期的设计要求。
The working mode of medical switching power supply was analyzed.The continuous adjustable high frequency switching power supply circuit of PWM mode was adopted,and the PWM control chip was selected.The main circuit of medical switching power supply was designed.To verify the rationality of the circuit design,the simulation test platform of switching power supply was established.The results showed that the circuit design of the scheme was reasonable and the expected design requirements was reached.
