Maglev【Traction / auxiliary converter】

The traction inverter is integrated with three traction inverter modules, the main purpose is to convert the harvested DC voltage into the inverter voltage three-phase voltage, used to control the traction motor to drive the vehicle for traction, inertia and braking conditions.Traction converter IGBT semiconductor device uses circulating water cooling for effective cooling, the inverter structure is very compact, through the internal and external cooling cycle, the heat of the inverter is effectively passed out to prevent overheating.The traction / auxiliary converter is integrated with two traction inverter modules and one auxiliary inverter module. In addition to the traction drive function, it also undertakes the function of auxiliary power supply, which can convert the DC voltage into three-phase sine wave voltage to supply the AC load of the vehicle. Small volume, high integration, large energy.
