Abstract: Performance of power electronic converters has become a major concern in the present day. Converters should be designed with the objective of gaining a high efficiency, increased reliability and less complexity. This paper presents the reliability analysis of three converters. Reliability of two-stage Interleaved boost converter, two-stage and single-stage PFC converter is measured. It is shown that number of components in a device effects the reliability of a system.

Keywords: Reliability. MTBF, Power factor correction.
