Digitally controlled switch mode power supply for charging rechargeable batteries










Image Number 6 for United States Patent #6031359.

A method of charging rechargeable batteries with a switch mode power supply, the method comprising determining one or more battery charging parameters, and controlling the power output of the switch mode power supply by digitally generating a gate signal for controlling opening periods and closing periods of a switching means of the switch mode power supply, each of the durations of the opening periods and the closing periods of the switching means, respectively, being determined in response to the determined one or more battery charging parameters and one or more charging process reference values. In particular, a method is proposed of controlling the duty cycle of a switch in the switch mode power supply during charging of the battery based on determinations of one or more characteristic charging parameters of the charging process and comparisons of determined parameter values with desired parameter values.
