Latest Patents

One of U-Fat Chio's latest patents is a mixed signal controller designed for a power quality compensator. This invention includes an analog circuit, an analog-to-digital converter (ADC), and a digital circuit. The analog circuit amplifies an input signal from the power quality compensator by a gain factor and outputs an analog signal, which is then converted to a digital signal by the ADC. The digital circuit processes this digital signal to calculate the reference compensating current for each phase and generates a trigger signal via hysteresis PWM to the power quality compensator. Additionally, the digital circuit features an evaluation circuit that calculates the system's total harmonic distortion after compensation and adjusts the gain factor when necessary.

Another notable patent involves a comparator that includes a comparing input unit and a latching unit. The comparing input unit receives two comparing signals and drives intermediate node signals based on these inputs. The latching unit determines the comparison result and latches it according to a second strobe signal, ensuring accurate and reliable performance.
