Latest Patents

Yao's latest patents include an "Error amplification apparatus and driving circuit including the same." This invention relates to an error amplification apparatus that utilizes a pulse generating circuit to produce first and second pulses based on the output voltage of an error amplification unit. A counting unit is coupled to the pulse generating circuit to count these pulses and generate a loop control signal representing a compensation voltage. This innovation effectively digitizes the compensation voltage, allowing for better control of the loop control signal's variation in AC cycles, thus simplifying peripheral design and reducing the capacitance of the compensation capacitor.

Another notable patent is the "Switch-mode power supply control apparatus and flyback switch-mode power supply including the control apparatus." This invention features a PWM controller that outputs a driving signal and includes a short-circuit protection module. The module detects zero-crossing detection voltage and determines if a short-circuit situation occurs, subsequently outputting a short-circuit signal to the PWM controller. This design ensures low power consumption during short-circuit protection, enhancing the efficiency of the flyback switch-mode power supply.
