Abstract

DC voltage operated electronic circuits are often polarity sensitive and require their battery source to be placed correctly or else possible damage may occur. A full-wave bridge diode circuit would allow battery placement regardless of polarity but would drop 1.4V if Silicon diodes are used and would result in significant power loss.
