Title: Innovations by Yi-Cheng Liu

Introduction

Yi-Cheng Liu is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of electronics, particularly in motor control systems. With a total of 7 patents to his name, Liu continues to push the boundaries of innovation in his industry.

Latest Patents

One of his latest inventions is a motor commutation testing circuit. This circuit is designed to determine when the motor commutation testing circuit enters a test mode. In this mode, a selector circuit chooses a commutation signal generating circuit, providing a simulated commutation signal to a control circuit. Additionally, when the testing circuit detects that the motor commutation testing circuit enters a rotation detection mode, the selector circuit selects a motor rotation detecting circuit. This circuit then provides a commutation signal of the motor to the control circuit.

Another notable invention is an automatic control system for the phase angle of a motor. This system includes a current detector circuit that detects the current signal of the motor and outputs a current detected signal. The control circuit then generates a control signal based on this detected signal, indicating the time point at which the current signal reaches a zero value. Subsequently, a driver circuit outputs a driving signal according to the control signal, allowing the output circuit to adjust the motor's rotational state based on the driving signal.
