Title: Sin-Li Lin: Innovator in Power Conversion Technology

Introduction

Sin-Li Lin is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of power conversion technology, holding 2 patents that showcase his innovative approach to electrical engineering.

Latest Patents

One of his latest patents is titled "Isolated converter with initial rising edge PWM delay." This invention involves a power converting device that includes a transformer, a first switch connected to the primary winding of the transformer, and a PWM controller that generates a first PWM signal. The controller also produces a control signal that leads the first PWM signal. Additionally, the device features a rectifier-filter circuit that rectifies an induced voltage from the secondary winding of the transformer, a second switch connected to the secondary winding, and a synchronous rectifier controller that manages the conduction of the second switch based on the control signal. This innovative design allows the second switch to become non-conductive before the first switch conducts.

Another significant patent by Lin is the "Power converting device and synchronous rectifier control circuit." This invention includes a main switch, a synchronous rectifier switch, and a rectifier-filter circuit that outputs an output voltage. The synchronous rectifier control circuit consists of a sampling circuit linked to the rectifier-filter circuit, which outputs a voltage variation signal. A differential amplifier circuit amplifies this signal by adding the output voltage and an offset voltage. A comparison circuit then compares the amplified signal with the output voltage to generate a trigger signal, ensuring that the synchronous rectifier switch operates efficiently in relation to the main switch.
