In the area of marine industry, there is a large interest in converters for high power density. Increasing power above 8MW; pf 0.8; 3, 3kV in Medium Voltage Drive leds to either increase voltage or associate drives in parallel. Both solutions consist in doubling the number of components to reach the same power density that means drives with higher footprints and expensive solutions. This paper presents...
This paper investigates in a topology of medium voltage inverter retained to guarantee severe conditions concerning environmental and reliability requirements. This system is based on a standard three levels NPC (Neutral Point Clamped) drive with redundant IGBT and can tolerate the on-state failure mode of the IGBT. Like this, in the operation mode the inverter has been designed to run in permanent...
Compared with DC traction application, AC electric traction is known to provide robust and low cost solution with high dynamic performances for an industrial vehicle. This embedded, compact and autonomous system is composed of a low voltage and high current induction motor (IM) fed by PWM voltage source inverter (PWM-VSI) supplied by an independent DC source (DCS battery). The authors propose the...
