   Policy measures to drive WBG for end use equipment
By Bjarke Spliid HANSEN [View]
[Download]

Abstract: This paper discusses different potential policy measures to support the WBG uptake in end use equipment. The EU product regulations and specifically the potential PV inverter efficiency requirements, are discussed, serving as an example. Standardisation, in various fields (test methods for reliability and efficiency, rules for environmental footprint, modules and package architecture) and economic support for creating a WBG ecosystem are considered as well. Implementation drivers and barriers are identified through stakeholder interviews highlighting specifically two barriers: knowledge gaps on reliability of WBG and lack of standardised components and product platforms for WBG. Theconclusion lists the potential policy measures identified and gives an outlook of the work.

Abstract: In this paper, we review some of the main methods to characterize on-state and off-state losses in wide-band-gap devices under switching conditions. In the off-state, we will discuss about losses related to charging and discharging the output capacitance in wide-band-gap devices, both in hard- and soft-switching. In the on-state, we will present an accurate measurement of dynamic on-resistance degradation, particularly in Gallium Nitride (GaN) devices. These losses are typically not described in data-sheets, but can be a dominant loss mechanism in power electronic applications.
