Relaxation of current filament due to RFC technology and ballast resistor for robust FWD operation
We have investigated the destruction mechanism of High Voltage (HV) Free Wheeling Diodes (FWD) during a reverse recovery operation. The most possible mode of the destruction phenomena originate in local heating due to current filament at the edge portion of the active area. To achieve a large reverse recovery Safe Operation Area (SOA), we focus on the boundary region between the active area and the termination area. To enforce our Relaxed Field of Cathode (RFC) concept [1, 2], it is more effective for the wider SOA to place a ballast resistance for avoiding the current from crowding around the anode region in the top surface of the diode.
