20200403400 | METHOD FOR AT LEAST PARTIALLY REMOVING OSCILLATIONS OCCURRING AT THE END OF A CURRENT DISCHARGE FOR AN H-BRIDGE - Disclosed is a method for at least partially removing the oscillations occurring at the end of a current discharge through the structural diodes for a switching structure supplying power to an inductive load in the form of an H-bridge and including two controlled high or low power switches forming part of a high circuit or a low circuit, respectively, between a respective output and a power source or a ground, the switching structure having one of its outputs below the ground potential and the other above the potential of the power source during the current discharge through the structural diodes. A detection or anticipation of the end of discharge and a forced preservation of a freewheel after the detection of the end of discharge are carried out, the forced preservation of the freewheel after the detection of the end of discharge taking place for a predetermined preservation time. | 2020-12-24 |
20200403401 | LIMITER CIRCUIT - A switch element is arranged between an input terminal and an output terminal. A signal from the input terminal is distributed by a capacitative element and supplied to the cathode side of a diode. An inductor is connected to the cathode side of the diode, and a smoothing circuit including a capacitative element and a resistor is connected to the anode side. The switch element has a control terminal connected to the anode of the diode, and turns off a path between the input terminal and the output terminal when a voltage is applied to the control terminal. | 2020-12-24 |
