Title: Innovations by Chen-Xiu Lin in Power Conversion Technology
Introduction
Chen-Xiu Lin is a notable inventor based in Zhubei, Taiwan. He has made significant contributions to the field of power conversion technology, holding 2 patents that showcase his innovative approach to circuit design and control methods.
Latest Patents
One of his latest patents is titled "Controller of Power Conversion Circuit and Operating Method Thereof." This invention involves a controller that generates PWM signals to manage output stage circuits, providing an output voltage and load current to an output terminal. The controller comprises a sensing circuit, a comparison circuit, a PWM generation circuit, and a control loop. The sensing circuit produces a current sensing signal related to the load current, while the comparison circuit evaluates this signal against a default value representing a current threshold. The control loop generates a trigger signal based on a reference voltage and the output voltage, controlling the PWM generation circuit. If the load current exceeds the threshold, the control loop temporarily halts the trigger signal to delay PWM signal generation.
Another significant patent by Chen-Xiu Lin is also titled "Controller of Power Conversion Circuit and Operating Method Thereof." This version focuses on a controller that works in conjunction with a smart power stage (SPS) to convert an input voltage into an output voltage while providing an output current. The SPS sends a current monitoring signal to the controller, which includes a control loop, a sampling circuit, and a current reconstruction circuit. The control loop generates a PWM signal to manage the SPS's operation, while the sampling circuit captures the current monitoring signal. The current reconstruction circuit generates a reconstructed current based on the input voltage, reference voltage, and PWM signal, calibrated using a calibration reference value.
