4.5 AFE for Insulation Monitoring in High-Voltage EV Charging and Solar Energy Reference Design

Ensuring the operational safety of a DC microgrid is mandatory for each system operator. The insulation monitoring reference design measures isolation resistance and insulation leakage from DC to protective earth in regular intervals using the electric bridge DC insulation monitoring (DC-IM) method. The signal chain, shown in Figure 4-6, is based on isolated data converters and isolated power switches and enables fast system evaluation, as it is compatible with the C2000 BoosterPack™ plug-in module.
