Proposed Backup Control for Bi-Directional Automotive 42 Volt to 14 Volt Converter 2001-01-2499

Previously, the power conversion operation of a bi-directional 42 volt to 14 volt converter for a dual voltage automobile electrical system was described in references 1 and 2.
Often, DC/DC converters are designed with protection circuits; both to protect the converter against external mishaps and to protect the external input and output connected devices against internal control loss. Here, the converter function would normally be under the control of an external computer. In this paper, an elementary directional control system is proposed as a backup in case of failure of the external power management computer.
