Latest Patents
Cheng Bao's latest patents include a "System and method for over voltage protection in both positive and negative polarities." This invention focuses on protecting measurement circuits from potentially energized devices under test (DUT). In one embodiment, the DUT is a capacitor that has acquired a charge prior to testing. The circuit he developed limits the current to the measurement circuit while dissipating the energy stored in the DUT. Additionally, a detection circuit measures the voltage at the DUT's terminal, ensuring that the measurement circuit connects only when the voltage is below a specific threshold.
Another significant patent is the "Power supply circuit and method for providing output voltage to charge a battery." This invention describes a charging device and method for charging a rechargeable battery. The device includes a current source coupled to a power source, providing a charging current to the battery. The controller regulates the current source to deliver a charging current that is less than what the battery requires in a given state, effectively bringing the output voltage closer to that of the rechargeable battery.
