Abstract
A voltage boosting method, system, and circuit which can be incorporated into a battery or device or can be added as a circuit that interfaces between a battery and a device. Optionally, the voltage boosting system can be added without requiring the battery or the device to be modified. The voltage boosting circuit incorporates a pair of transformers and does not require a step-up transformer, thus enabling the circuit to be constructed in a compact form, optionally within a single integrated circuit package. One or more mechanical or automatic switches can be provided which enable the voltage boosting circuit to be disconnected from the battery and the load until such time as the voltage of the battery or battery bank falls below a predetermined amount, at which time the one or more switches can be activated, thus engaging the voltage boosting circuit.
