AC powered systems such as onboard chargers (OBC) are divided into two or more voltage domains that are galvanically isolated from each other. For example, one high-voltage domain includes the AC grid, DC link, and the power stage for power-factor correction (PFC). A second high-voltage domain contains the DC bus and high-voltage battery. The PFC controller is referenced to DC link (–) and measures the value of the AC line voltage while remaining galvanically isolated from the AC mains for functional reasons. With the high-impedance input and galvanically isolated output, the AMC0x30R-Q1 enables this measurement.
