Automotive High-Voltage and Isolation Leakage Measurements Reference Design
Description
The function of this reference design is to monitor the isolation resistance of a high-voltage bus to the chassis ground. Monitoring the isolation strength of coupling devices and components from high voltage to the chassis ground is a necessary feature in HEV’s and EV’s as battery management systems: traction inverters: DC/DC converters: onboard chargers: and other subsystems operate at high voltage (greater than 60 V).
