摘要：dc to dc converter (10) operates according to a predetermined period ofoperation (a) of a primary circuit and a predetermined level of current and the detectedcurrent (is) of a secondary battery to produce a better load capacity, and a long lifeurea.the energy is stored in the primary (14) and a driver (12), when the primary power isprovided by a battery (20) to the internal impedance (24) varies during the life of thebattery is started for a predetermined period of the.at the end of the period that thepower is cut off, and the stored energy is transferred to the secondary (16) through aprocess of resetting to zero, whereby a storage capacitor (28). as a means of prevention(56) to prevent a premature initiation of primary power (14) after the expiration of theperiod.the energy storage cycle is repeated when the power is detected at thesecondary level falls below a predetermined minimum threshold of a current (imin).
