This reference design features an Electric Bridge DC Insulation Monitoring (DC-IM) method; which allows for an accurate symmetrical and asymmetrical insulation leakage detection mechanism, as well as an isolation resistance detection mechanism.
This design is based on a new generation of isolated amplifiers and switches which enable an isolated measurement without an additional isolated supply on the hot side. Instead the whole design is powered from the cold side. The insulation monitoring diagnostic can be added to an existing power conversion or charging protocol microcontroller (MCU).
