Latest Patents

One of his latest patents is a "Battery charging circuit with improved system stability and control method thereof." This patent describes a control method for managing a battery charging circuit that includes at least one switch. The method involves generating a first difference signal based on the difference between a charging current feedback signal and a charging current reference signal. It also includes generating a bias reference signal by proportionally integrating the first difference signal when the battery voltage is between two thresholds. Furthermore, it generates a comparison signal by comparing the sum of the system voltage feedback signal and a ramp signal with the sum of a bias signal and a system voltage reference signal. Ultimately, a control signal is produced to manage the switch based on the comparison signal and a constant time period control signal.

Another patent by Ma is also titled "Battery charging circuit with improved system stability and control method thereof." This method involves generating a second difference signal based on a battery voltage feedback signal and a battery voltage reference signal. Depending on the battery voltage, it selects one of the first and second difference signals, along with a ground voltage as a third difference signal. A bias signal is generated by proportionally integrating the third difference signal, and a control signal is produced to manage the switch based on the comparison signal and a constant time period control signal.
