Abstract: The object of the invention is to provide a power supply system and method for the various elements forming DC/AC electronic power converters that assures the operation of the converters during normal operating conditions and anomalous operating conditions, being specially designed for photovoltaic systems connected to the power grid and capable of providing direct current and alternating current voltages at the output thereof from at least one DC power source (1) and at least one AC power source (2), which basically comprises an output for DC loads (6) connected to the output of a DC/DC converter (3) the input of which is connected to the DC power source (1), an AC output for critical loads (7) connected to a first selector (5) configured for alternating between a first position where said AC output for critical loads (7) is connected to the output of a first DC/AC converter (4) the input of which is connected to the DC power source (1), and a second position where said AC output for critical loads (7) is co

Abstract: The present invention relates to a control system and control method for controlling a switching device (1) integrated in an electronic converter, the object of which is to extend the working voltage range of the switching devices and thus increase the power of the electronic DC/AC converter which prepares the energy produced by a energy generating system and injects it into the electrical grid. It basically comprises a voltage source (3), a capacitance (7), a first gate resistor (21) and a second gate resistor (22), a first circuit formed by a series resistor (6) with a first diode (5), a second circuit formed by a second diode (4) and a connecting element (8) controlled by a control unit (12) that controls the opening and closing thereof. Another object of the present invention is a switching cell for an electronic converter comprising said control system.
