Patent number: 10788802Abstract: Some appliances, normally supplied by a mains supply, also comprise an emergency supply by batteries able to take over from the mains supply. The batteries used by the emergency supply are generally protected by a fuse. These appliances are liable to consume greater than what could be supplied by the batteries of the emergency supply. When there is a break in the mains electrical supply, it is then preferable to limit the current consumed by the appliance in order not to damage the fuse protecting said batteries. However, the fuses are hardware modules having a reaction time of a few hundreds of milliseconds. If it is wished not to damage the fuse, it is therefore essential to reduce the current consumption of the appliance within a time less than the reaction time of the fuse. The invention relates to a system and method for instantaneously reducing the electrical consumption of an appliance in the event of a break in the mains supply.Type: GrantFiled: November 22, 2017Date of Patent: September 29, 2020Assignee: SAGEMCOM BROADBAND SASInventors: Jean-Philippe Negele, Anthony Reuche, Massinissa Lalam

Patent number: 10568168Abstract: A lighting system includes a power supply unit, a power conversion unit, a lighting unit, a first switching unit, and a first reset unit. The power supply unit is used to supply a first and a second power signal. The power conversion unit receives and converts the first power signal. According to the first power signal, a first lighting module of the lighting unit emits light. The first switching unit is connected to a first node between the first lighting module and a second lighting module for receiving the second power signal, so that the second lighting module emits light according to the second power signal. The first reset unit receives the second power signal; wherein when the second lighting module changes from lighting to no lighting, the first reset unit causes the power conversion unit to stop operating and then restart.Type: GrantFiled: February 27, 2019Date of Patent: February 18, 2020Assignee: Chicony Power Technology Co., Ltd.Inventor: Chen-Chi Lin

Patent number: 10536004Abstract: A system includes an output terminal to couple to an electrical load and a plurality of power supplies coupled in parallel. Each of the power supplies includes a controller configured to monitor a power output of a downstream power supply and a power output of an upstream power supply, maintain a standby state of the power supply in response to the downstream power supply providing power below a first threshold value, transition the power supply to an voltage regulation state in response to the downstream power supply providing power above the first threshold value, and provide a maximum power in response to the upstream power supply providing power above a second threshold value. The standby state represents a state in which a power output of the power supply is 0%, and the voltage regulation state representing a state in which the power output of the power supply is above 0%.Type: GrantFiled: February 28, 2017Date of Patent: January 14, 2020Assignee: Raytheon CompanyInventor: David C.

Patent number: 10523027Abstract: Provided is a power supply apparatus including a power storage module, a DC-AC inverter, a bypass circuit, and a controller. The DC-AC inverter converts output of the power storage module into AC power. The bypass circuit directly transmits the AC power. The controller switches between a discharge mode for supplying output of the DC-AC inverter to a load, and a bypass mode for supplying output of the bypass circuit to the load. A threshold for switching between the discharge mode and the bypass mode is set to a range that enables the power storage module to provide output in an overload state.Type: GrantFiled: March 18, 2015Date of Patent: December 31, 2019Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Naoyuki Sugeno, Hiroaki Yoshida, Kazumi Sato, Koji Umetsu
