Mass transit auxiliary power systems perform multiple functions. These include stabilizing AC power to drive on-board compressors for air conditioning, brakes and lighting; and generating high stability DC power to charge the vehicle’s batteries and feed other DC loads. Advances in semiconductor technology and battery design are providing direct benefit to the transportation industry through flexible mechanical design, reduced maintenance and reduced design cycles.
Power electronics used in auxiliary inverters and battery chargers must keep energy losses to a minimum. Powerful solutions from Rogers keep these systems running with greater reliability and efficiency.
Within the IGBT and MOSFET power modules of auxiliary power systems, power substrates provide interconnections and cool components. curamik® ceramic substrates are designed to carry higher currents and provide higher voltage isolation ROLINX® busbars distribute power for auxiliary power units in Mass Transit applications.
