Bridge and capacitor, wherein transformer output end connects high-frequency rectification bridge input terminal；High-frequency rectification bridge output end shunt capacitance is just
Cathode, the capacitor and accumulator load circuit in parallel.
Circuit as described above, the capacitance are 3300UF.
In foregoing circuit structure, the accumulator load circuit include: with the concatenated optical coupling switch element of battery and
Field-effect tube, under the control of impulse generator, the pulse frequency to control the on-off of the accumulator load circuit.
In foregoing circuit, the optical coupling switch element model TLP521.
The utility model is led to by the current mode combined harmonic generated to generate resonance with lead-acid accumulator crystalline solid
The sulphur crystalline solid on resonance removing battery terminal is crossed, and then improves the comprehensive discharge capability of battery pack；Battery is repaired in acquisition
Multiple efficiency reaches 95%；Also, this programme belongs to lossless reparation to the reparation of battery, does not damage battery pole plates.
