Latest Patents

One of Che-Wei Chang's latest patents is a "Switching converter having pulse skipping mode and control method thereof." This invention includes a power stage circuit, a feedback control circuit, an operating signal generator circuit, and a pulse skipping circuit. The feedback control circuit generates an initial pulse width modulation (PWM) signal according to the output power. The operating signal generator circuit masks a part of the clock signal's pulses based on the pulse width of a pulse skipping signal, resulting in an adjusted PWM signal. The pulse skipping circuit adaptively generates a duty ratio signal based on input and output voltages, creating a pulse skipping reference signal related to the initial PWM signal's duty ratio. The power stage circuit then converts the input power to output power according to the adjusted PWM signal.

Another notable patent is the "Sliding rail," which is designed to engage with an engaging member. This invention features a track and a limiting mechanism. The track consists of a base wall, two side walls, and two pivoting slots. The limiting mechanism includes first and second operating members, a limiting member, and first and second connecting members. The first operating member drives the limiting member from a locked position to an unlocked position, allowing the engaging member to move freely. The second operating member performs a similar function, enhancing the versatility of the sliding rail design.
