Latest Patents
One of Jae-Hong Joo's latest patents is titled "Two stage architecture for a monitor power supply." This invention features a power supply that comprises two stages. The first stage acts as a power factor corrector, achieving greater than 95% power factor correction and providing a range of outputs from approximately 5 volts to 200 volts with excellent load regulation at low voltages. The second stage is a soft switching power supply that maintains good load regulation from approximately 40 to 175 volts. The innovative design allows for extremely good line regulation and low regulation by utilizing an intermediate high voltage from the first stage to supply the second stage.
Another significant patent is the "Soft-switching power supply with auxiliary resonator." This converter employs a multifilar transformer with primary and auxiliary windings created simultaneously through a technique known as bifilar winding. This method ensures high efficiency and low noise by minimizing leakage inductance and reducing the proximity effect. The improved soft-switcher topology further enhances performance by reducing interwinding capacitance. A resonant LC circuit is integrated into the design to optimize switch loss and resonant pulse loss.
