Latest Patents

Ke Shen holds a patent for a "High-performance control method for carrier-based modulation T-type three-level converters." This invention relates to a sophisticated control method that includes several key steps. It represents the mathematical model of the converter using the switching function. The method also represents the three-phase modulation signal using the sine function and the upper and lower carrier signals using a piecewise function. Furthermore, it determines the time distribution of the converter's switching state and obtains the critical phase shift angle of the lower carrier under specific conditions. The method samples voltage values of two DC-side capacitors and uses the voltage difference to adjust the lower carrier. Finally, it compares the three-phase modulation wave with the upper and lower carriers to output the switching pulse signal. This innovative method effectively addresses neutral-point potential balance, common-mode voltage suppression, and reduces the resource usage of digital processors during PWM modulation.
