ABSTRACT:
A transformerless battery charger having a circuit for connecting the battery to an A.C. power source to supply charging current to the battery including: an inductive impedance in series with the battery for limiting the charging current through the battery. An electronic switch in the form of a TRIAC or SCR is connected in series with the battery, and the electronic switch is normally non-conductive thereby keeping open the charging circuit for the battery. An electronic trigger for turning on said electronic switch is provided to close the charging circuit for the battery as a function of the difference between the instantaneous voltage from said A.C. power source and the battery voltage. The electronic switch and the electronic trigger jointly operating to provide a pulsed charging current to the battery during the A.C. power cycle which is long enough to produce a significant battery-charging effect but short enough to avoid harmful internal heating of the battery. The electronic trigger advantageously includes an R--C element driving a Diac.
