This work presents a study of the influence of different gate driver circuits on the switching behavior and EMI produced by SiC MOSFET devices used in a boost converter. The paper includes several simulations of switching behavior using different VGS voltage levels and different passive RCD (Resistance Capacitor Diode) circuits to interface the driver to the SiC MOS gate and several tests of conducted...
This paper discusses a novel design of Power Distribution Network (PDN). By physical structuring of the power plane into repetitive symmetrical and asymmetrical segments of varying size, suppression of the propagation of unwanted noise throughout the PDN over a wide frequency range is achieved. Prototype boards were built on standard FR4 and thin FR4 substrates and characterized using a Vector Network...
This paper investigates the safety consequences of the use of EMI filters on board ships. Ship's power supply systems differ from their land-based counterparts but there are no special “EMI filters for ship-board use” on the market. The paper shows that the level of protection against electric shock is severely undermined when normal EMI filters are applied on board ships.
