The subject of the invention is a method of PV panels diagnostic in PV panels system (1) using a solar inverter (3) for detecting at least one failed panel in the photovoltaic power system. The inventive method comprises the step of measuring output voltage signals Ucoming out from out the PV panel system (1), a step of processing measured signals Udc by using the FFT, a step of delivering to the control inverter unit (6) constant values, the step of creating fingerprints (F1, F11; ..... Fn-1, Fnn) for each pair of the two consecutive DC link voltage Udc measurement Udc(n-1) and Udcn for each output voltage signals from the panel system (1), the step of comparing the amplitudes of at least one pair of fingerprints (F1, F11;......Fn-1, Fnn) of the measured voltage signals with a value from the set of frequencies chosen by the user and determine a fault indicator Fand a step of automatically triggering a command for the control unit (6) to warn or alarm stop for the inverter unit (4).

The present disclosure relates to a high voltage power electronics module (1) for subsea applications. The power electronics module (1) comprises: a baseplate (3), a power semiconductor chip (7) arranged on the baseplate (3), and an encapsulation structure (5) arranged on the baseplate (3) and configured to encapsulate the power semiconductor chip (7), wherein the encapsulation structure (5) is an epoxy having an elastic modulus less in a range of 1 to 20 Giga Pascal, GPa, at room temperature and a coefficient of thermal expansion less than 20 ppm/K.

Technologies for individualized building automation include a building automation application server (102), a building controller (106), and several mobile computing devices (104). Each mobile computing device generates individualized sensor data based on the time and location of the mobile computing device and sensor data indicative of a building system control parameter. The sensor data may include temperature data, humidity data, or other environmental data, and may be received by the mobile computing device from one or more external sensors. The building automation application server (102) receives the individualized sensor data from the mobile computing devices (104) and generates a building system configuration based on the individualized sensor data. The building automation application server may optimize the building system configuration for cost, efficiency, or user comfort based on the individualized sensor data. The mobile computing devices (104) and the building automation application server (102) may communicate via one or more collection servers (112).

A gate drive circuit and a method for controlling a gate-controlled component (30), the gate drive circuit comprising a PI controller (31) adapted to receive an input reference signal (v ref,d/dt ) and to control a gate voltage of the gate-controlled component. The gate drive circuit comprises a first feedback loop for the PI controller (31), the first feedback loop comprising first gain (k v ), a second feedback loop for the PI controller (31), the second feedback loop comprising second gain (k i ). The second feedback loop comprises a clipping circuit (32) adapted to modify a feedback signal in the second feedback loop during turn-on of the controlled component (30) when the time derivative of the collector current is negative and the first feedback loop comprises a first blanking circuit (101) adapted to cut the feedback loop when the controlled component is in a blocking state.
