Title: Innovations of Shang-Kay Yang

Introduction

Shang-Kay Yang is a prominent inventor based in Taoyuan, Taiwan. He has made significant contributions to the field of power electronics, holding a total of 8 patents. His work focuses on enhancing the efficiency and performance of power supply systems.

Latest Patents

One of his latest patents is an electromagnetic interference suppression method. This method is designed for at least one power supply, which includes a first conversion circuit and a second conversion circuit. The first conversion circuit receives an input voltage and outputs a first output voltage, while the second conversion circuit receives the first output voltage and outputs a load current. If the input voltage is a DC voltage, an electromagnetic interference suppression operation is performed. This operation determines whether the load current is greater than a preset current and lower than an upper current limit. If the conditions are met, the first output voltage is dynamically adjusted, ensuring that the peak-peak value of the first output voltage is not zero with varying load current.

Another notable patent is a power converter and method of operating the same. This power converter includes a power factor correction (PFC) circuit and a controller. The controller acquires a switching frequency based on the instantaneous value of the input voltage and determines upper and lower limit frequencies based on the effective value of the input current. When the effective value exceeds a medium load threshold, the operation mode of the PFC circuit is switched to optimize performance.
