Latest Patents

Kwan's latest patents include a "Method and apparatus for charge pulse-width modulation control." This invention involves a charge mode pulse-width modulation control method that utilizes a detector at the primary side of a transformer to monitor current. The detected current is fed back to a current apparatus, which provides a current output. An integrator then supplies charge output with a voltage mode, implementing mathematical integration to produce an output voltage. This output voltage serves as a reference for a main controller, ensuring that the transformer avoids magnetic saturation and minimizes noise in the feedback control current signal.

Another significant patent is the "Current detection method for DC to three-phase converters using a single DC sensor." This method allows for the detection and calculation of three-phase alternating currents using only a single DC sensor. It can determine the direct current value of one phase across six different gate states of three pairs of transistors in the DC to three-phase AC converter. The method effectively calculates the current value of the other phases based on the principle that the sum of the three-phase currents is always equal to zero.
