Abstract
An access assembly for a high voltage box or inverter which reduces the associated risk of exposure to charged components, such as high voltage power electronics, where an interlock is required. The access is limited so that the system may deactivate some functionality, and/or internal devices are discharged to allow safe access. The access assembly includes a wireless detection method using a sensor circuit paired with a magnet that detects if a cover or connector is removed. The magnet is mounted to the cover or connector. This detection may be made through walls of non-magnetic material, which avoids the incorporation of extra components such as PCBs or a pigtail harness, enables a much simpler EMC shielding by avoiding unwanted openings, and simplifies assembly by reducing required operations and processes. The access assembly may be used for applications where controlled access is required for installation or service of power electronic products.
