Latest Patents

One of his latest patents is titled "Method and system for balancing multi-phase LLC power converter with switch-controlled capacitors." This invention involves a multi-phase LLC power converter that includes several LLC phases, each equipped with a resonant tank and a switching stage. The resonant tank consists of a resonant inductor, a resonant capacitor, and a parallel inductance. The switching stage operates at a specific frequency to apply a switched power to the resonant tank, approximating an alternating current (AC) waveform. A secondary-side controller adjusts the switching frequency to manage the output voltage, while a primary-side controller measures currents and calculates the conduction phase angle for each LLC phase to ensure equal resonant frequencies.

Another significant patent is "Power converter with integrated multi-layer cooling." This invention features a power converter that incorporates an integrated multi-layer cooling structure. It consists of multiple printed circuit boards (PCBs) arranged vertically, with a liquid cooling mechanism attached to the lowest PCB. High loss circuitry components are mounted on one side of this PCB, while low loss components are placed on additional PCBs. The cooling mechanism actively cools the high loss components, while the low loss and magnetic components are passively cooled.
