Patent number: 10804692Abstract: A solid-state circuit protector includes a first power semiconductor device having an ON resistance that increases with increasing temperature and a second power semiconductor device connected in parallel with the first power semiconductor device having an ON resistance that decreases with increasing temperature. During times when abnormally high currents are flowing through the solid-state circuit protector, the second power semiconductor is switched ON so that some or all of the current is diverted through it, thus protecting the first power semiconductor device from being damaged due to overheating. The first power semiconductor device is either switched OFF, allowing it to cool in anticipation of a lighter load, or is configured to remain ON so that it shares the burden of carrying the high current with the parallel-connected second power semiconductor device yet operates cooler and at a lower ON resistance since it is not required to pass the full current.Type: GrantFiled: June 1, 2018Date of Patent: October 13, 2020Assignee: Atom Powers, Inc.Inventors: Ryan Kennedy, Denis Kouroussis

Patent number: 10784061Abstract: A dynamically coordinatable electrical distribution system includes a plurality of intelligently-controlled protection devices (PDs), a communication and control bus (comm/control) bus, and a central computer. The plurality of intelligently-controlled PDs is configured to protect a plurality of associated electrical loads from faults, developing faults, and other undesired electrical anomalies. Each of the PDs further has electrically adjustable time-current characteristics. The intelligently-controlled PDs are communicatively coupled to the comm/control bus and configured to report current data representative of real-time currents flowing through their respective loads to the central computer, via the comm/control bus. The central computer is configured to communicate with the plurality of PDs over the comm/control bus and dynamically coordinate the time-current characteristics of the plurality of PDs based on the current data it receives from the PDs.Type: GrantFiled: January 28, 2019Date of Patent: September 22, 2020Assignee: Atom Power, Inc.Inventors: Ryan Kennedy, Denis Kouroussis

Patent number: 10630069Abstract: A solid-state circuit interrupter and arc prevention device (SSI/APD) is disclosed. The SSI/APD is designed to be configured in series with a mechanical circuit breaker and serves to interrupt current flowing through the circuit it is protecting upon a short circuit being detected or if an overload has persisted for an inordinate amount of time. The SSI/APD is capable of detecting and responding to faults in a matter of microseconds and detects and responds to faults on its own, without requiring the mechanical circuit breaker to trip. The mechanical circuit breaker can be optionally tripped after the SSI/APD has opened the circuit. However, the mechanical circuit breaker is tripped only after the SSI/APD has interrupted the circuit, so electrical arcing across the circuit breaker's contacts is avoided. The SSI/APD can also be reset remotely after a fault has been cleared, obviating the need for a person to be present to reset it.Type: GrantFiled: October 3, 2017Date of Patent: April 21, 2020Assignee: Atom Power, Inc.Inventors: Ryan Kennedy, Denis Kouroussis

Publication number: 20200083699Abstract: A hybrid air-gap/solid-state device protection device (PD) for use in an electrical power distribution system includes an air-gap disconnect unit connected in series with a solid-state device, a sense and drive circuit, and a microcontroller. Upon the sense and drive circuit detecting an impending fault or exceedingly high and unacceptable overvoltage condition in the PD's load circuit, the sense and drive circuit generates a gating signal that quickly switches the solid-state device OFF. Meanwhile, the microcontroller generates a disconnect pulse for the air-gap disconnect unit, which responds by forming an air gap in the load circuit. Together, the switched-OFF solid-state device and air gap protect the load and associated load circuit from being damaged. They also serve to electrically and physically isolate the source of the fault or overload condition from the remainder of the electrical power distribution system.Type: ApplicationFiled: November 14, 2019Publication date: March 12, 2020Applicant: Atom Power, Inc.Inventors: Ryan Kennedy, Denis Kouroussis

Patent number: 10530156Abstract: A method and system of power factor optimization and total harmonic distortion are provided under the premise of efficient power management and distribution on an electrical grid. The method and system include a novel optimization technique based on a novel current profiling methodology enabling real-time power management with power factor correction as a function of the optimization. The optimization can be performed under dynamic current constraints. When deployed on an electrical grid, the method and system can provide a new technique for power management targeting an efficiency of the electrical grid. The method and system can thus provide for reduced costs of energy production and reduced carbon emissions into the atmosphere.Type: GrantFiled: December 10, 2018Date of Patent: January 7, 2020Assignee: Volta Energy, Inc.Inventors: Denis Kouroussis, Emre Kulali

Publication number: 20190341213Abstract: In an electrical distribution system including a solid-state circuit breaker (SSCB) and one or more downstream mechanical circuit breakers (CBs), a solid-state switching device in the SSCB is repeatedly switched ON and OFF during a short circuit event, to reduce a root-mean-square (RMS) value of the short circuit current. The resulting pulsed short circuit current is regulated in a hysteresis control loop, to limit the RMS to a value low enough to prevent the SSCB from tripping prematurely but high enough to allow one of the downstream mechanical CBs to trip and isolate the short circuit. Pulsing is allowed to continue for a maximum short circuit pulsing time. Only if none of the downstream mechanical CBs is able to trip to isolate the short circuit within the maximum short circuit pulsing time is the SSCB allowed to trip.Type: ApplicationFiled: April 12, 2019Publication date: November 7, 2019Applicant: Atom Power, Inc.Inventors: Denis Kouroussis, Ryan Kennedy

Patent number: 10429914Abstract: Multi-level data center using consolidated power control is disclosed. One or more controllers communicate with one or more power supplies and sensors to adapt to dynamic load requirements and to distribute DC-power efficiently across multiple IT racks. The distributed DC-power includes one or more DC-voltages. Batteries can be temporarily switched into a power supply circuit to supplement the power supply during spikes in power load demand while a controller reconfigures power supplies to meet the new demand. One or more DC-to-AC converters handle legacy power loads. The DC-to-AC converters are modular and are paralleled for redundancy. The DC-to-AC converters are sourced from the one or more AC-to-DC converters. The AC power is synchronized for correct power flow control. The one or more controllers communicate with the one or more AC-power supplies to dynamically allocate AC-power from the DC-to-AC converters to the multiple legacy IT racks.Type: GrantFiled: October 20, 2017Date of Patent: October 1, 2019Assignee: Virtual Power Systems, Inc.Inventors: Karimulla Raja Shaikh, Ravi Subramaniam, Denis Kouroussis, Rajeev P Huralikoppi, Ryan Justin Kennedy, Erich Karl Nachbar, Shankar Ramamurthy, Pranthik Samal, Rajaram Soundararajan, Andrew Sy

Patent number: 10128684Abstract: Disclosed are systems and methods to provide energy control via power-requirement analysis and power-source enablement. Both demand-side and supply-side techniques are used alone or in conjunction to determine an optimal number of power sources to supply power to one or more loads. When fluctuations in power requirements are present, measures such as decoupling less-critical loads in order to continue delivering power to critical systems and turning on and off power sources as needed to meet the current power demands of a system are implemented. Power sources are periodically deactivated by the system on a rotational basis such that all power sources wear evenly, prolonging the life of the equipment. A scalable architecture that allows the virtualization of power from the underlying hardware form factor is also provided.Type: GrantFiled: October 28, 2014Date of Patent: November 13, 2018Assignee: Virtual Power Systems, Inc.Inventors: Shankar Ramamurthy, Sushant Shankar, Rajaram Soundararajan, Andrew Sy, Andrew L Wang, Erich Karl Nachbar, K David Lin, Frank Chuang, Rajeev P Huralikoppi, Ryan Justin Kennedy, Denis Kouroussis, Milind Kukanur, Pranthik Samal
