Latest Patents
Yan-Zheng Yang holds a patent for a Mixed Signal Controller developed for a power quality compensator. This mixed signal controller includes an analog circuit that amplifies input signals from the power quality compensator while outputting an analog signal. An analog-to-digital converter (ADC) then transforms this analog signal into a digital format. The digital circuit subsequently calculates the reference compensating current for each phase and produces a trigger signal using hysteresis pulse-width modulation (PWM) to optimize the performance of the power quality compensator. Additionally, the digital circuit features an evaluation circuit that assesses the system's total harmonic distortion after compensation and adjusts the gain factor accordingly when specific thresholds are met.
