Title: Innovations of Yueqiang Zhou
Introduction
Yueqiang Zhou is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of power conversion technology. With a total of 2 patents, his work focuses on enhancing the efficiency and performance of power conversion devices.
Latest Patents
One of his latest patents is a power conversion device that includes a power conversion unit designed to convert power into AC power with a predetermined frequency and voltage. This device utilizes a switching operation involving multiple switching elements. It features a DC unit that comprises a capacitor and a reactor, along with a controller that manages the switching operation. The capacitor plays a crucial role in smoothing out the ripple caused by the switching operation. The controller is adept at monitoring an indicator value that correlates with disturbances affecting the input current supplied to the power conversion unit. It compensates for control variables based on frequency components that are integral multiples of the power source frequency.
Another significant patent by Zhou is a power converter that effectively reduces vibration and noise in motors caused by pulsation in the direct current link voltage. This invention includes an inverter circuit that converts a pulsating direct current link voltage into alternating current, which is then supplied to a permanent magnet synchronous motor. The controller in this system employs vector control to manage the inverter circuit, ensuring that the phase of the resultant voltage vector varies according to the pulsation.
