SBASAT2 December 2024 AMC0386
PRODUCTION DATA
AC-line powered power supplies are divided into two or more voltage domains that are galvanically isolated from each other. For example, the high-voltage domain includes the AC grid, DC-Link, and the power stage for power-factor-correction (PFC). The low-voltage domain includes the system controller and human interface. The PFC controller must measure the value of the AC line voltage while remaining galvanically isolated from the AC mains for safety reasons. With the high-impedance input and galvanically isolated output, the AMC0386 enables this measurement.
