Interior permanent magnet synchronous motor (IPMSM) systems are vulnerable to uncontrolled generation (UCG) when the inverter switches loss their drive signals suddenly during field weakening high speed operation. At this point, uncontrolled rectifier-like inverter is composed by six freewheel diodes, the current comes from the motor through the rectifier-like inverter and converter, then charges...
