Title: High frequency switching battery charger

Abstract

A power supply is described for charging a storage battery which consists of: power supply means adapted to be connected to a source of electrical energy for supply power; rectifying means operatively connected to the power supply means for rectifying the supplied power; output transformer means operatively connected to the rectifying means and to the battery for transforming the rectified power; power switching means operatively connected to the output transformer means for controlling a flow of current from the rectifying means through the output transformer means; pulse width modulator means operatively connected to the power switching means for controlling the power switching means, with a coupling transformer interposed between the pulse width modulator means and the power switching means; current sensing means for sensing the flow of current through the output transformer means; current limiting means responsive to the current sensing means and operatively connected to the pulse width modulator means for controlling the pulse width modulator means; charging voltage control means responsive to the current sensing means and operatively connected to the pulse width modulator means for controlling the pulse width modulator means; latch means for stopping the pulse width modulator means operatively connected to the pulse width modulatormore » means; overcurrent sensing means responsive to the current sensing means operatively connected to the latch means for controlling the latch means; means for sensing the absense of the storage battery operatively connected to the latch means for controlling the latch means; and end-of-charge sensing means operatively connected to a terminal of the battery and to the latch means for controlling the latch means responsive to a predetermined voltage present at the terminal.« less
