Latest Patents

Mao Cyuan Jian holds a patent for a DC-to-DC step-up converter and its associated conversion method. This invention introduces a logic control unit designed to minimize the ripples in the DC output voltage, thereby improving overall power quality. The converter comprises several key components, including a step-up circuit, a ring oscillator, a divider circuit, a pulse frequency modulation (PFM) comparator, and the logic control unit. The step-up circuit effectively increases the source voltage to produce a stable DC output voltage. The ring oscillator generates an oscillator output signal, while the divider circuit creates a feedback voltage from the DC output. The PFM comparator plays a crucial role by comparing the feedback voltage with a reference voltage to control the output of the oscillator signal. The logic control unit ensures that the conductive period of a MOS transistor in the step-up circuit aligns with the high-level period of the ring oscillator's output signal, significantly reducing noise and ripple in the converter's output.
