Energy-storage pulse device

Abstract

An energy storage pulse device includes a first inductor and a second inductor, the two terminals of the first inductance are respectively connected with one end of the first voltage stabilizing tubeand the second voltage stabilizing tube, a first common contact is arranged between the first inductance and the positive electrode of the second voltage stabilizer tube, two negative electrodes of the first voltage stabilizer tube and the second voltage stabilizer tube are connected to form a second common contact, and a second inductance, a battery and a third voltage stabilizer tube after beingconnected in parallel are arranged in series between the first common contact and the second common contact, and the second inductance value is larger than the first inductance. When the energy storage pulse device receives the RF read-write signal, a large inductive current is generated on the first inductor in the direction of the second inductor, and the third voltage regulator is turned off,and the second inductor increases the voltage to charge the battery; and when the RF read-write signal is received, the first inductor generates a large inductive current in the direction of the second inductor. When the voltage across the second inductor is greater than the reverse breakdown voltage of the third transistor, both the first inductor and the second inductor are in a short circuit state, the third transistor is turned off in the reverse direction, and the first inductor and the second inductor are turned on forward. As that first inductor acquire electrical energy, the battery iscontinuously charged with the acquire energy during the RF reading process. The structure can be charged by radio frequency signal, and the structure is simple and compact.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to an energy storage pulse device. Background technique [0002] Existing energy storage typically takes a few minutes to charge a tiny battery.
