Title: Innovations of Chien-Yu Chi
Introduction
Chien-Yu Chi is a notable inventor based in Taoyuan, Taiwan. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced motor driving systems. With a total of 4 patents to his name, Chi's work focuses on enhancing the efficiency and performance of inverter systems.
Latest Patents
Chi's latest patents include a "Circulating current and oscillating current suppressing method and parallel inverter driver system." This invention discloses a method where each inverter driver outputs a suppressing three-phase current to a motor. It incorporates both an entity inductance device and a virtual inductance device. The virtual inductance device sums the suppressing three-phase current from the inverter drivers and generates a compensated three-phase current. This innovation effectively reduces the oscillating current outputted from the inverter driver’s switch device. Additionally, the circulating current suppressing device generates a corrected three-phase voltage command to suppress zero-sequence and circulating currents in the parallel inverter driver system.
Another significant patent is the "Motor deceleration method and motor driving system using the same." This method provides a way to control the descent speeds of voltage and frequency values during motor deceleration. By generating a voltage compensation value based on current comparisons, the system ensures that the motor's rotating speed gradually decreases to a preset level.
