ABSTRACT:
A DC to DC converter particularly suited for use to boost or reduce the voltage with single battery systems allows insertion of the battery in either polarity through use of a symmetrical arrangement of solid-state switches which alternate charging an inductor for the DC to DC converter operation and establishing a ground depending on the polarity of the battery. The use of a solid-state switch to establish a ground avoids the severe voltage drop required of rectifier systems.
