Abstract
The invention relates to an analog isolation device () comprising a primary part () and a secondary part () separated by an electrical isolation barrier, these parts including a high-frequency channel configured to produce a high-frequency component in the secondary part and a low-frequency channel configured to produce a low-frequency component in the secondary part, in order to form the output signal from the high-frequency and low-frequency components, the device further including a control circuit (D) configured to receive, in the primary part, a setpoint signal (S) and a so-called image signal (S) representative of the output signal (S) and to apply in the high-frequency and/or low-frequency channel a correction signal Vas a function of the difference between the image signal and the setpoint signal in order to cause that difference to tend toward zero.
