Experimental exploration of functional integrity, functional reliability and reliability of modern power electronics equipments
Energy flow from source to load via electrical domain involves dual conversion and makes loads inefficient. The status has changed once energy is channelled through power electronic equipments. Their function spaces are beyond just achieving functionality as more loads are under active control and grid is enabled to deliver its potential. Multiple topologies exist to achieve mere functionality. Equipments should possess high functional reliability and reliability. Switching frequency is one critical parameter for active control of load. Higher switching frequency needs soft-switching topology. Parametric significance changes with topology and so is its worst-case design. Their influence in high speed circuit with or without proper feedback affects quality engineering parameters. This paper presents experimental approaches to find functional integrity at different levels in product to achieve functional reliability and reliability.
