What is auxiliary inverter charger (AIC)?
Auxiliary Inverter Charger (AIC) * Electric Vehicle (EV) and Plug-in Hybrid Electric Vehicle (PHEV) have been globally developed to realize sustainable world. An on board charger is required for charging at home, but it is not necessary to bring the charger while driving. The on-board-charger becomes only `weight’ while driving vehicles.
Why do we need auxiliary inverter?
Smaller in volume and lighter in weight for charger is achieved with a modification of existing auxiliary inverter. No additional cooling unit such as cooling liquid pipe, air duct, fan etc. is required for charger function. And important bidirectional charging function can be easily realized easily with software control. 2.
What are auxiliary converters?
Our auxiliary converters are the crucial link between these consumers and the vehicle‘s power supply. Thanks to its standardized module concept, the SiC-based system creates entirely new potentials in the design of auxiliary converters with a platform concept for metro, commuter, and high-speed rail.
Which auxiliary inverter should be used as a charger?
Compared with a traction-motor inverter, an auxiliary inverter, which is independent from driving, braking and steering, is a good candidate as a charger. Secondary, power ratio between charger (3kW) and inverter should be in the same range.
What are the benefits of a 12V auxiliary Axis?
Auxiliary axis at 12V will move to higher voltage allowing loss and cost reduction. Main benefit is for high power systems like the HVAC, Power steering and PTC-heater; Power Electronic companies like electrification: the market for HV switches, modules, gate drivers and motors will grow with a high pace rate in the next 6 years and onwards.
Why do inverters have fluid cooling equipment?
Original inverter drives auxiliary motor while driving. Therefore, the inverter has fluid cooling equipment so as to cool the inverter even when the engine produces maximum power and heat. AIC uses this cooling system in the motor drive mode. Energy for this cooling system is of-course required.
