Latest Patents

One of his latest patents is titled "Self-driven synchronous rectifier by retention of gate charge." This invention introduces a synchronous rectifier that utilizes a gate charge retention technique. It addresses the issue of lost driving voltage in self-driven synchronous rectifiers, which typically leads to high conduction losses through the body diode. By employing this method, the synchronous rectifier remains operational even after the main transformer is reset, thus avoiding the effects of leakage inductance and achieving high efficiency across various circuit topologies.

Another significant patent is the "Noise canceling apparatus for a power converter." This apparatus employs magnetically-coupled windings to effectively cancel out noise currents or voltages generated by a power converter. It can include either a series voltage source or a shunt current source positioned at the input or output terminals to eliminate unwanted noise.
