His innovative work has led to the creation of a unique patent that enhances the efficiency of power conversion systems.
Latest Patents
Zhen Qin Luo holds a patent for an "Asymmetric-amplitude dual-polarity charge pump with four-phase selectable operation." This invention features a symmetric dual-voltage charge pump and its control circuit, which generates bipolar output voltages. The charge pump is designed to convert a unipolar power source into a set of dual-voltage outputs of opposite polarity that operate independently. The system includes two voltage-boosting transfer capacitors and two output capacitors. The two-phase operation allows for an increased-magnitude output voltage of negative polarity, while another two phases generate an increased output voltage of positive polarity. This innovative charge pump selectively charges one or both bipolar outputs using individual 2-phase charge cycles or a sequence of charge cycles. By utilizing comparators with unequal reference voltages, the charge pump can produce unequal positive and negative voltages, enhancing the speed of charge pumping.
