Interleaved boost converters having several stages, can be used to increase the reliability. So in this paper, a reliability comparison is done between the conventional boost converter and the interleaved structure. Two different operation modes are defined for the interleaved boost converter: half-power and full-power operation modes. The reliability calculation is based on the Markov model of the converters. The power loss effect of converter components on their failure rates, and therefore, on the reliability of converter has been assessed. For the first time different failure rates have been considered for different operation modes. Also a laboratory prototype of a two-stage interleaved boost dc–dc converter has been built up and the failure rate of components in different operation modes are calculated practically. Results show that in addition to other benefits, interleaved structure has higher reliability and as the power increases, there will be a decrease in the reliability.

Many articles have studied different aspects of interleaved boost converters. For instance, development of a high-efficiency dual-input interleaved dc–dc converter for reversible power sources to convert low-voltage reversible power sources to a high-voltage dc bus individually or simultaneously by the phase-shift control. A novel multidevice interleaved boost converter that interfaces the fuel cell with the power train of hybrid electric vehicles is proposed. A fault-diagnostic method is introduced for three-phase interleaved dc–dc converters using only the dc-link current derivative sign features. To achieve high step-up gain, an interleaved winding-coupled boost converter is proposed. A two-phase interleaved boost converter is used as critical conduction mode power factor corrector, which uses a variation-tolerant phase shifter to ensure accurate 180° phase shift between the two interleaved converters. Application of interleaved dc–dc boost converters for the photovoltaic generation system and a maximum power point tracking controller is proposed

A boost converter (step-up converter) is a DC-to-DC power converter with an output voltage greater than its input voltage. It is a class of switched-mode power supply (SMPS) containing at least two semiconductors (a diode and a transistor) and at least one energy storage element, a capacitor, inductor, or the two in combination. Filters made of capacitors (sometimes in combination with inductors) are normally added to the output of the converter to reduce output voltage ripple.

The failure rate of converter components are calculated for different operation scenarios. Also the power loss effect on the failure rate of components and on the reliability of converters is discussed

For the interleaved structure, half-power and full-power operating scenarios have been considered. The effect of power loss has been assessed on the temperature, which is a stress factor in the reliability analysis. Then, the failure rate of converter components has been calculated based on their power loss in different scenarios. The results show that with an increase in power, the reliability of components, and thereby, the reliability of the whole converter decreases.Also the interleaved boost converter operating in both scenarios is more reliable in comparison to the conventional boost converter.
