概述 随着人们对城市环境的日益关切，电动汽车的发展得到了一个难得的机遇。在城市交通中，电动大客车由于载量大，综合效益高，成为优先发展的对象。电动大客车大都采用三相交流电机，由于电机功率大，三相逆变器中的器件需要承受高电压和大电流应力的作用，较高的dv/dt又使电磁辐射严重，并且需要良好的散热。 而采用多重
概述随着人们对城市环境的日益关切，电动汽车的发展得到了一个难得的机遇。在城市交通中，电动大客车由于载量大，综合效益高，成为优先发展的对象。电动大客车大都采用三相交流电机，由于电机功率大，三相逆变器中的器件需要承受高电压和大电流应力的作用，较高的dv/dt又使电磁辐射严重，并且需要良好的散热。而采用多重串联型结构的大功率逆变器则降低了单个器件承受的电压应力，降低了对器件的要求；降低了dv/dt值

驶。但大功率逆变器会产生频率范围为100.0kHz至200.0MHz的电磁干扰。这些逆变器的高功率交流和直流转换让混合动力车的电磁干扰问题更为严重。 相比之下，在将交流电转换为直流电，为电池组充电时，电子设备的重量较轻，因而相较于变压器其性能更为优越。实际上，电子设备是当前适用于交直流电转换、以电池组推动车辆行驶的唯一的可行技术。但是，这些电子设备会产生更多的电磁干扰，因为高电压线束会充当
千瓦的功率。如今，150千瓦的充电站需要约30分钟才能为电动汽车充入足够的电量，并使其行驶约250公里。设计一个可以处理如此大功率的单功率处理单元需要采用难以控制的复合多级拓扑结构。 在现代充电站中，一种将功率输出缩放到快速充电所需电平的方法是使用并联堆叠的模块化功率转换器。由于直流充电站占用了大量空间，因此功率转换器必须是模块化的，且针对高效率和高功率密度进行了优化。 电池组有两条
