Latest Patents

Gabsu Seo's latest patents include a hybrid converter with reduced inductor loss. This innovative converter achieves high efficiency by positioning the inductor in the lower current path, which significantly decreases inductor loss by reducing the DC component of inductor current. The design also features a reduced inductance requirement, which minimizes the voltage swing blocked by the inductor. This results in improved efficiency and better integration, along with less voltage stress for switches, which reduces switching loss and allows for increased switching frequency. Consequently, this enables a reduction in the size of passive components. The circuit can be utilized for both step-down and step-up power conversion, as well as bidirectional power flow. For simplicity and cost-effectiveness, some switches can be replaced with passive switches such as diodes, simplifying the converter circuit implementation.

Another significant patent is the hybrid converter family and methods thereof. This disclosure provides methods and circuits that utilize a combination of a switched multiple capacitor network and several inductors for power conversion. This approach is particularly beneficial for applications requiring a large conversion ratio, high output current, low output voltage, and/or high input voltage. The disclosed circuits and methods can be applied to modern switching regulators, allowing them to deliver the same power conversion function with fewer power conversion stages, smaller passive components, and fewer active components. This not only reduces implementation space but also improves efficiency. Sample applications include point-of-load power converters for data centers, telecommunication systems, and other high-performance electronic systems.
