Publication number: 20230403822Abstract: In the past, several microchannel configurations were developed to realize two-phase cooling for high-power electronics, but these were limited to small devices with sizes at ˜cm length. It has been a challenge to implement effective two-phase cooling to large devices with a length of ˜10 cm due to notorious scaling effects. Here, we devised a novel channel configuration to achieve effective two-phase cooling on devices with an area of ˜10 cm by ˜5 cm or larger, which is the prevailing size of major commercial electronics and power electronics devices. In a lab environment, we demonstrated that the novel channel configuration can meet their cooling needs.Type: ApplicationFiled: November 4, 2022Publication date: December 14, 2023Inventors: CHEN LI, WEI CHANG, ENRICO SANTI, BO TIAN

Patent number: 11740268Abstract: Systems, apparatuses, methods and computer processes to separate and select frequency components of a signal in real time without phase delay by predicting or forecasting future values of the signal and using that forecast and past measurements in a noncausal zero-phase filtering algorithm are provided. The method of separating and selecting frequency components of a signal in real time without phase delay using a zero-phase filter, comprises obtaining past measurements of the signal; obtaining predicted values of the signal; and using the predicted values of the signal and the past measurements of the signal as components of an input signal in a noncausal zero-phase filtering algorithm for a zero-phase filter, the zero-phase filter producing an output signal.Type: GrantFiled: April 20, 2021Date of Patent: August 29, 2023Assignee: University of South CarolinaInventors: Andrew S. Wunderlich, Enrico Santi

Patent number: 10819215Abstract: Many DC applications switching converter modules are multilevel, series connected converters. If an individual converter cell fails, it is desirable to be able to bypass the failed cell, in order to continue operating the rest of the converter. A bypass switch is provided as a hybrid switch, including a parallel combination of a slow mechanical switch with high current conduction capability and a low power semiconductor switch with faster acting switching capabilities. When the bypass switch is activated (closed), the low power semiconductor switch is turned on first and quickly establishes the bypass within 10 ?s or less, to temporarily conduct required current until the slower mechanical switch turns on. The mechanical switch is subsequently turned on with zero voltage, given the parallel-connected semiconductor switch being on. If desired, the semiconductor switch can then be turned off with zero voltage, given the presence of the mechanical switch.Type: GrantFiled: June 28, 2017Date of Patent: October 27, 2020Assignee: University of South CarolinaInventor: Enrico Santi

Patent number: 5969484Abstract: A discontinuous conduction mode (DCM) electronic ballast topology is presented which drives the lamp with line frequency voltage and current, just like a magnetic ballast. However, compared to magnetic ballast, its weight is substantially reduced due to operation at high switching frequency (40 kHz in the experimental prototype). The topology also ensures unity power factor at the input and stable lamp operation at the output.Type: GrantFiled: May 14, 1998Date of Patent: October 19, 1999Assignee: Optimum Power Conversion, Inc.Inventors: Enrico Santi, Zhe Zhang, Slobodan Cuk

Patent number: 5790005Abstract: In a dc-to-dc converter, input and output inductors loosely coupled and isolation transformer windings closely coupled are implemented on a UI magnetic core in such a manner as to satisfy a zero-ripple condition k.sub.1 =n of current in the output inductor, where n is a turns ratio of the loosely coupled input and output inductors, and both inductors are chosen to have the same number of turns, and that number is an integer such that the value of the coupling coefficient k.sub.1 required to satisfy the zero-ripple condition is one achieved by modeling of core leakages instead of by adjusting the turns ratio n, thus making it feasible to implement the coupled inductors, and the transformer windings as well, in a single UI core and modeling the core losses by configuring the core.Type: GrantFiled: June 24, 1996Date of Patent: August 4, 1998Assignee: Optimum Power Conversion, Inc.Inventors: Enrico Santi, Slobodan Cuk
