Patent number: 10505367Abstract: Aspects and embodiments described herein are directed toward a power interface device including a first power interface configured to couple to an electric utility and a second power interface configured to couple to a microgrid comprising one or more power sources and one or more loads, the one or more power sources including a generator. The power interface device also includes a power conversion circuit coupled to the first power interface and the second power interface and a controller coupled to the power conversion circuit. The controller is configured to allow interfacing between the electric utility operating at a first frequency and voltage and the microgrid operating at a second frequency and voltage by at least detecting an operating frequency of the generator and controlling a power flow between the electric utility and the microgrid based on the operating frequency of the generator.Type: GrantFiled: August 21, 2013Date of Patent: December 10, 2019Assignee: SCHNEIDER ELECTRIC IT CORPORATIONInventor: Patrick Chambon

Patent number: 10110011Abstract: An uninterruptible power supply (UPS) system (100) comprises a plurality of UPS units (UPS-1, UPS-2) connected in parallel. Each UPS unit comprises a power converter (124) for supplying a share (i load 1, i_load_2) of a total load current (i_tot). The total load is shared automatically between UPS units of power ratings, in a proportionate manner. A controller 130 of each converter is arranged to establish real-time feedback control of a current supplied by the power converter. An exchange current (i_exch) for each converter represents an imbalance between an output current of the converter in question and output currents of the parallel converters. Exchange current sensing circuits of the parallel-connected UPS units are connected together. The controller steers the exchange current of each converter toward a value (i_exc_c) that is a non-zero proportion of a current (i_mut) sensed within the converter.Type: GrantFiled: January 5, 2012Date of Patent: October 23, 2018Assignee: SCHNEIDER ELECTRIC IT CORPORATIONInventors: Daniel Rozand, Patrick Chambon, Stefano De Cesaris

Patent number: 9584045Abstract: The present disclosure relates to a controller, a circuit and method for controlling a power converter using pulse width modulation (PWM). At least one logic block (13, 15, 16) of the controller is configured to remove a command (4) which is configured to control the other power semiconductor switch (2) in a half-bridge (1,2) so that the other power semiconductor switch (2) remains in a non-conductive state while an antiparallel diode (6) allows an electric current (5) to pass in one direction, called the diode's forward direction, while blocking current in the opposite direction. In case the diode (6) is conducting instead of the other power semiconductor switch during the duration of the state of the command, the switching command (4) for the latter is omitted.Type: GrantFiled: January 5, 2012Date of Patent: February 28, 2017Assignee: SCHNEIDER ELECTRIC IT CORPORATIONInventors: Daniel Rozand, Patrick Chambon, Stefano De Cesaris
