Latest Patents

One of his latest patents is an "Apparatus for charging both main battery and auxiliary battery using the same primary winding and two different secondary windings of a single transformer." This battery charging apparatus includes a converting unit, first and second charging units, and a switching unit. The converting unit separately converts AC power into a first voltage and a second voltage. The first charging unit drops the converted first voltage to charge a high voltage battery, while the second charging unit drops the converted second voltage or a third voltage of the high voltage battery to charge an auxiliary battery. The switching unit operates in two modes, allowing for efficient charging of both batteries.

Another significant patent is a "Charger for electric vehicles," which features a wide output voltage range. This slow charger is designed with an improved configuration to handle varying output voltages and changes. It achieves limited switching loss and reduced noise through soft-switching operation, enabling high-efficiency large-power Power Factor Correction (PFC) and enhancing the conversion efficiency of a DC/DC converter.
