Latest Patents

One of his latest patents is the "Three-phase single-stage soft-switching AC-DC converter with power factor correction." This invention achieves power factor correction with low phase voltage switch stress. Direct input current sensing is performed to calculate the average input current of the AC-DC converter and implement power factor correction. The embodiments feature high power factor, single-stage power conversion, and soft-switching of all switches, resulting in high conversion efficiency in a cost-effective single-stage three-phase structure. The converters have low output voltage ripple without a double line frequency component, which allows non-electrolytic capacitor implementation. These converters are particularly useful in high-power applications such as electric vehicle charging.

Another notable patent is the "Generation method for programmable analog fringe pattern with extended depth of field." This method involves a laser emitting a laser beam that is focused and collimated with a collimating lens. The collimated Gaussian laser beam is reflected by a mirror, passes through a round diaphragm, and is incident on a MEMS scanning mirror. The beam is reflected by the MEMS scanning mirror to the surface of a tested object. The laser is controlled by a sinusoidal current signal generated by a drive board to sinusoidally modulate the brightness of the laser beam. The MEMS scanning mirror is stimulated by a drive signal generated by the drive board to turn two-dimensionally, thus driving the laser beam to perform scanning and generate a fringe pattern image.
