Latest Patents

One of Terng-Wei Tsai's latest patents is the "Totem-pole power factor corrector with zero-voltage switching." This innovative device receives an input power source and converts it into an output power source. The design includes an input inductor, a fast-switching switch leg, a slow-switching switch leg, a resonant tank, and an output capacitor. The fast-switching switch leg features both a fast-switching upper switch and a fast-switching lower switch, which are coupled at a first middle node. The slow-switching switch leg operates in parallel to the fast-switching switch leg and includes a slow-switching upper and lower switch. The resonant tank consists of a resonant inductor and at least one resonant capacitor, facilitating efficient power conversion.

Another notable patent is the "Power conversion system with ripple injection and power conversion control method." This system includes an AC-DC conversion unit, a voltage regulation unit, multiple DC-DC conversion units, and at least one load. The voltage regulation unit provides a DC link and utilizes a portion of the input power for energy storage. Each DC-DC conversion unit receives the remaining input power as output power, which is supplied to the corresponding load. The first control unit manages the DC link, the DC-DC conversion units, and the load, adjusting the ripple magnitude of the output power based on the input power's ripple.
