Abstract
A boost regulator circuit includes a rechargeable power supply Vcc, an energy storage component 22 coupled to the rechargeable power supply, a load C.sub.L, and a bi-directional drive means (S1-S6, 20 and 27) for delivering energy from the energy storage component 22 to the load C.sub.L. The bi-directional drive means allows energy transferred to the load to be recovered back to the rechargeable power supply Vcc before switching the load C.sub.L in an opposite direction, thereby effectuating an efficient management of energy and extending the life of the rechargeable power supply Vcc.
