Title: Jiyao Wang: Innovator in Electrical Engineering
Introduction
Jiyao Wang is a prominent inventor based in Madison, WI (US). He has made significant contributions to the field of electrical engineering, particularly in the development of advanced inverter technologies. With a total of 2 patents, Wang's work has the potential to impact various applications in the industry.
Latest Patents
Wang's latest patents include innovative designs for series connected DC input inverters. This multi-level converter features a first multi-phase inverter and a second multi-phase inverter. The first inverter is equipped with a first direct current (DC) positive line, a first DC negative line, and a first plurality of alternating current (AC) lines. Each AC line is designed to connect to a single phase winding of an electric machine, which is configured in either a Y-winding or a Δ-winding arrangement. The second multi-phase inverter mirrors the first, with its own DC lines and AC connections. Notably, the first DC negative line is electrically coupled to the second DC positive line, allowing for a series connection between the two inverters.
Another significant patent involves methods for determining the initial position of a rotor in a drive system. This system includes a motor with a rotor that receives a measured current. A controller generates a voltage for the motor, and a filter extracts position information based on the measured current. A nonlinear observer estimates the rotor's position during a stationary reference frame, enabling the controller to manage the motor effectively based on this estimated position.
