Reliability consideration for a high power single switch flyback power supply

In this paper, a high power single switch flyback power supply is presented. Performance of this power supply in continuous conduction mode is investigated in implementation. An appropriate efficiency is achieved by designing a proper snubber circuit. With regard to the importance of reliability in switch mode power supplies, reliability consideration is discussed for this high power flyback in details. This paper demonstrates the flyback topology has suitable failure rate in high power applications because it has only one power switch.
