Publication number: 20200168600Abstract: The invention aims for a polarisation circuit of a power component comprising a capacitive dividing bridge and a resistive dividing bridge formed on the same substrate as the component. An additional electrode 1? in the front face 100 of the substrate makes it possible to adjust one of the capacitance values of the capacitive dividing bridge according to the other of the capacitance values coming from one of the electrodes of the power component. The sizing of this additional electrode furthermore makes it possible to obtain a leakage resistance contributing to the resistive dividing bridge. Alternatively, two additional resistances R, R? formed in the front face of the substrate making it possible to obtain the resistive dividing bridge independently of the capacitive dividing bridge.Type: ApplicationFiled: October 30, 2019Publication date: May 28, 2020Applicant: Commissariat A L'Energie Atomique et aux Energies AlternativesInventors: Julien BUCKLEY, Erwan MORVAN
