Title: Yi-Chen Lin: Innovator in AC Signal Production and Motor Driving Technology

Introduction

Yi-Chen Lin is a notable inventor based in Pingtung, Taiwan. He has made significant contributions to the field of electrical engineering, particularly in the development of technologies related to AC signal production and motor driving methods. With a total of 2 patents, Lin's work addresses critical challenges in these areas.

Latest Patents

One of Lin's latest patents is an AC signal producer and method thereof. This invention comprises a controlling unit, a Class-D switch circuit, and a low-pass filter. The control unit receives a DC signal and produces a PWM control signal by checking reference tables. The Class-D switch circuit then receives the PWM control signal and outputs a square-wave signal, which the low-pass filter converts into an AC signal. This innovation effectively resolves the disadvantages associated with using an oscillator and a transformer to convert DC signals to AC signals.

Another significant patent by Lin is a driving apparatus and a driving method for a single-phase motor. This invention utilizes a driving transistor unit and an auxiliary driving transistor unit to provide two driving currents in the same direction as the single-phase coil. A control unit manages the conducting and shutting down of these units based on the location of the rotating device of the single-phase motor. This design reduces vibration and noise while preventing issues related to the motor not turning on.
