在油电混合动力汽车(HEV,Hybrid-Electric Vehicles)中不管是交流/直流或是直流/直流电压转换器都是相当关键的构建方块,如主电池的高电压大约200V~800V,混合动力汽车通常使用直流/直流转换器把电压由高电压电池升压以提供电动汽车电机动力,另一方面,直流/直流转换电路也可以把主电池电压转换为低电压,如用来进行辅助电池充电和提供附属电路电源的12V电压,或者作为其他各种操作用途的5V、15V和24V电压。在可插电混合动力汽车中,交流/直流转换器可由市电取得进行电池充
In the HEV (Hybrid-Electric Vehicles) whether AC / DC or DC / DC voltage converter is a key building blocks, such as the main battery high voltage of about 200V ~ 800V, hybrid electric vehicles DC / DC converters are often used to boost the voltage from a high-voltage battery to provide electric vehicle motor power. On the other hand, the DC / DC converter circuit can also convert the main battery voltage to a low voltage, such as for auxiliary battery charging and 12V for auxiliary circuit power supply, or 5V, 15V and 24V for various other applications. In pluggable hybrid vehicles, AC / DC converter can be obtained from the electricity for battery charging
