Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A battery charger to supply a constant power to a battery while charging the battery, said battery charger comprising: rectifying means for producing rectified alternating current when receiving an input of alternating current; comparator means having an inverting input, a non-inverting input and an output; means for providing a predetermined voltage to the inverting input of said comparator means from said rectified alternating current; means for providing a predetermined DC voltage to the non-inverting input of said comparator; a constant power regulator with an output to be connected to the battery; switching means operatively connected between said constant power regulator and said rectified alternating current; and control means operatively coupled between said switching means and the output of said comparator means, said control means activates said switch means for a predetermined time, determined by the output from said comparator, to allow the rectified alternating current to reach a desired voltage across said constant power regulator at which time said control means deactivates said switch means, wherein the value of the desired voltage is determined by the voltages input to the comparator means.
Claim 2
Dependent Claim
182 words
A battery charger to supply a constant power to a battery while charging the battery, said battery charger comprising: rectifying means for producing rectified alternating current when receiving an input of alternating current; comparator means having an inverting input, a non-inverting input and an output; means for providing a predetermined voltage to the inverting input of said comparator means from said rectified alternating current; means for providing a predetermined DC voltage to the non-inverting input of said comparator; a constant power regulator with an output to be connected to the battery; switching means operatively connected between said constant power regulator and said rectified alternating current; and control means operatively coupled between said switching means and the output of said comparator means, said control means activates said switch means for a predetermined time, determined by the output from said comparator, to allow the rectified alternating current to reach a desired voltage across said constant power regulator at which time said control means deactivates said switch means, wherein the value of the desired voltage is determined by the voltages input to the comparator means.
