开关型稳压电源系统可靠性的研究

The Study on the Reliability of Switchingmode Power Supply Systems

对影响开关型稳压电源可靠性的主要因素、铝电解电容器、开关管的安全工作期作了详细分析后，提出了一种利用升压变流器及采取适当的调制方式来降低损耗，提高开关电源的可靠性的方法。

In this paper,the main factors affecting the reliability of switchingmode power supply,and the reliable working period of aluminium electrolytic capacitor and power switching transistor are discussed.An approach using boost converter and appropriate modulation mode to reduce the loss and to improve the reliability of switchingmode power supply is proposed.
