The paper shows the design in low-cost HV-CMOS technology of an integrated DC/DC converter for a 48 V electrical belt system generator-alternator used in micro/mild hybrid vehicles. Aiming at interfacing the 48 V power domain with a lower voltage domain, but without using cumbersome inductors and transformers, difficult to integrate in CMOS technology, the DC/DC converter exploits a multi stage architecture. Each stage is a switched capacitor unit. Multiple voltage outputs are supported with a configurable regulation factor, so that the same converter acts in step down or step up mode sustaining an input voltage variation from 6 V (in case of cranking) up to 60 V.

Abstract

The paper shows the design in low-cost HV-CMOS technology of an integrated DC/DC converter for a 48 V electrical belt system generator-alternator used in micro/mild hybrid vehicles. Aiming at interfacing the 48 V power domain with a lower voltage domain, but without using cumbersome inductors and transformers, difficult to integrate in CMOS technology, the DC/DC converter exploits a multi stage architecture. Each stage is a switched capacitor unit. Multiple voltage outputs are supported with a configurable regulation factor, so that the same converter acts in step down or step up mode sustaining an input voltage variation from 6 V (in case of cranking) up to 60 V.
