With a total of 3 patents to his name, Yang continues to push the boundaries of innovation in his field.
Latest Patents
One of Yang's latest patents is a "Voltage balance control method and device for three-phase DC-AC inverter." This invention provides a comprehensive voltage balance control method that includes several steps, such as multiplying an actual value of line capacitance voltage by a sine function to generate a first voltage. The method captures a DC part of this voltage to create an error DC component, which is then subtracted from a target voltage amplitude to generate a second voltage. This process involves adjusting the second voltage to produce an amplitude error compensation value, ultimately leading to the generation of an amplitude reference value.
Another notable patent is the "Sensorless measurement method and device for filter capacitor current by using a state observer." This device comprises a chip that includes a state observer configured to retrieve actual values of filter-capacitor voltage and direct current link voltage at the present sampling time. The state observer outputs various state variable values, including filter-capacitor-voltage and current state variable values, which are essential for accurate measurements without ripples.
