Latest Patents

One of Liu's latest patents is titled "Constant on-time (COT) control in isolated converter." This invention describes a constant on-time isolated converter that includes a transformer with primary and secondary sides. The primary side connects to an electronic switch, while the secondary side connects to a load and a processor. The processor generates a control signal based on the output voltage or current across the load, allowing for precise regulation of the output voltage and current via the transformer. This design achieves a high-speed load transient response by determining the ON/OFF state of the electronic switch based on the control signal's transitions.

Another notable patent is "Voltage detection circuit and a method of detecting voltage changes." This invention relates to a detection circuit implemented in an AC-DC power converter, which detects voltage changes. The AC input voltage is rectified to produce a DC input voltage, which is then processed by a detection unit to generate a detection voltage signal. This signal corresponds to different logical states based on input voltage changes, allowing for effective monitoring and response to voltage fluctuations.
