Solid state charging circuitry using a loading coil

摘要: Self-regulating solid state battery charging circuitry which automatically provides a rippled constant mean fast charge current irrespective of the condition and changes to trickle in response near-full-charge voltage. On-off triggering supply occurs error signals from sensing resistance is series with low-loss loading coil, receiving energized coil through diode during off intervals thereby achieve high efficiency. Only frequency shape ripples change as becomes charged. In voltage increased about 10-fold, resulting 10fold reduction 10-fold increase ripples.
