Radiated noise from an AC drive cable is a source of interference with adjacent systems that is often easier to identify and rectify than common mode noise. In the latter, high levels of noise across a broad frequency range, often from 60 Hz to 30 MHz, can capacitatively couple from the windings of the motor to the motor frame, and then to ground.
HMI stands for Human Machine Interface and HMI is a term and not an application.
HMI is the communication/interaction layer between the user and the process.
In the process industry the "Human" is the operator and the "Machine" is the process control data and instruments. HMI is not a term exclusively used for processes but you can find the HMI in any system.
I have been involved in the design for production of many power electronic products, including switching power supplies, electronic ballasts and automotive electronics for Hybrid vehicles. What I have found is the consistency of the breakdown voltages is different for AC and DC. I've sampled 100 ballast from a high volume production line. 50 of the units were subjected to a slow ramp to a sufficiently high DC Hipot breakdown voltage. The other 50 units were subjected to the same ramp but with AC.
