Abstract: A control system of a polyphase power converter has a regulation device configured to generate a control parameter that includes a drive setpoint value or a pulse duration associated with the drive setpoint value of at least one phase situated in a non-linearity zone of a chart and a control optimization system configured to receive the control parameter generated by the regulation device to control the polyphase power converter to deliver a balanced voltage system. The control optimization system modifies each phase of the control parameter so that it is in a linearity zone of the chart. The control parameter of each of the phases is modified in the same manner.

Abstract: Provided is a modular multilevel converter and a method for synchronizing outputs of sub-modules of the converter. The modular multilevel converter includes sub-modules connected in parallel, and each sub-module generates an output. The modular multilevel converter also includes a controller that is communicatively coupled to the sub-modules. The controller controls a flow of one or more synchronizing signals between the plurality of sub-modules, such that each sub-module receives the synchronizing signals in opposite directions simultaneously, thereby controlling a synchronization of the outputs generated by the sub-modules.

Abstract: This electrical protection system for a DC-current medium-voltage electrical circuit, comprising a disconnection module, for generating a counter-voltage greater than the voltage of the source for a current flowing therethrough that is equal to at most a few percent of the nominal current of the device, a resistive limitation module connected between a first terminal and a second terminal and configured so as to reduce the intensity of the output current of the protection system in order to limit the current between a value and upon a low impedance fault downstream of the device, and a primary switching module coupled in parallel across the disconnection module and the resistive module. The primary switching module is configured so as to switch between a first state in which the primary switching module is conductive and a second state in which the primary switching module forms a short circuit. Control means for controlling the primary switching module are configured so as to switch the primary switching module as soon as the current flowing in the first terminal reaches an upper limit value as lower value or a lower limit as upper value.

Abstract: A method of controlling of a polyphase power converter driven by an algorithm of the pulse width modulation type, in which a control parameter comprising a drive setpoint value or a pulse duration associated with a value of drive setpoint of at least one phase, situated in a non-linearity zone of a chart, is modified by modifying the value of said parameter so that it is in a linearity zone of the chart. The control parameter of each of the phases is modified in the same manner.

Abstract: An electrical system forming part of a solar power plant is described. The electrical system includes a plurality of photovoltaic (PV) panels, a power converter, and a controller. In response to a detected electric arc on the DC side of the power converter, the controller is configured to enable a short circuit state of the power converter by controlling semiconductor switches of the power converter (e.g., turning on some or all of the semiconductor switches) to create a short circuit between DC input terminals of the power converter. The short circuit path though the power converter will extinguish the detected electric arc in the connected DC circuit.
