[Introductionof Solution]

Thelocomotive traction inverter provides the direct current of 600V to theinverter and the charging case through the bus.

TheDC600V inverse power supply of the air conditioner converts the DC600V into thethree-phase AC 380V required by the air conditioner and the heater.

The8KW charger converts the DC600V into DC110V so as to respectively supply powerto electrical control, illumination, the backup battery and the singleinverter.

The 3.5KVA singleinverter inverts the DC110 of the charger into the alternative current of220V-50Hz required by vehicle ventilation, audio and visual equipment andsockets.
