Latest Patents
Xiangxu Yu's latest patents include a "Bias and discharge system for low power loss start up and input capacitance discharge." This invention describes a power supply that incorporates an AC input, a filter, a full wave rectifier, a converter, a second rectifier, and a bias system. The filter features at least one differential capacitor connected to the AC input. The full wave rectifier generates a DC bus voltage on a DC bus node, while the converter, which includes a controller, converts the DC bus voltage to a regulated output voltage. The second rectifier is linked to the AC input to create a DC bias voltage on a DC bias node. The bias system connects the DC bias node to a reference node, providing at least one start-up voltage to the controller. Additionally, the bias circuit includes a current discharge path for discharging each differential capacitor within a specified time frame when the AC line voltage is removed.
Another notable patent is the "Power supply with low power consumption hiccup standby operation." This invention features a power supply that includes a converter, a capacitance, and a hiccup control module. The converter transforms an input voltage into both an output voltage and a preliminary standby voltage during its active state. The capacitance stores the preliminary standby voltage, which is charged to an upper voltage level when the converter is active and discharged to a lower voltage level when inactive. During standby mode, the hiccup control module operates the converter in hiccup mode, alternating between inactive and active states based on the preliminary standby voltage levels. This innovative hiccup mode eliminates the need for a separate standby converter.
