Patent number: 11616441Abstract: Described is a new partial power converter (PPC) for the DC-DC stage of rapid-charging stations for electric vehicles (EV). The proposed converter manages only a fraction of the total power delivered from the grid to the battery, which increases the general efficiency of the system and the power density while potentially reducing the cost of the charger. The proposed topology is based on a switched capacitor between the AC terminals of a bridge converter H and does not require high-frequency isolation transformers in order to provide a source of controllable voltage between the CC link and the battery. The proposed concept can be implemented by using interposed power cells, which can improve energy quality, reduce the size of the inductor, and allow scalability for chargers of higher nominal power.Type: GrantFiled: September 21, 2018Date of Patent: March 28, 2023Assignee: UNIVERSIDAD TÉCNICA FEDERICO SANTA MARÍAInventors: Samir Felipe Kouro Renaer, Sebastián Andre Rivera Iunnissi, Álvaro Daniel Pesántez Alvarado

Patent number: 11304965Abstract: Flavonoids that are isolated from plant material of the genus Cecropia can be used to perturb G-protein coupled receptors in a mammalian cell. In some instances, one or more flavonoids may interact with one or more of the G-protein coupled receptors to transiently increase the concentration of cytosolic calcium. Administration of the isolated flavonoids can be used to treat hypertension, to protect the integrity of blood vessels and related conditions.Type: GrantFiled: October 28, 2020Date of Patent: April 19, 2022Assignee: Instituto de Investigaciones Cientificas y Servicios de Alta TecnologiaInventors: Catherina C.
