为了减少温室效应气体的排放，人们对燃料电池混合动力汽车进行了大量的研究。燃料电池电动汽车的动力总成由燃料电池、可充电储能装置、升压斩波器和双向斩波器组成。燃料电池混合动力汽车功率变换器的小型化是人们所期待的。因此，交错配置在转换器尺寸方面具有优势。本文研究了交错并联升压斩波器与燃料电池的驱动特性和双向斩波器与双电层电容器的驱动特性。这就要求双向斩波器采用考虑双电层电容器荷电状态（SOC）的控制方法。本文提出了一种考虑SOC的双电层电容器控制方法，并给出了混合动力电动汽车斩波器在三种状态下的驱动特性。作为实验结果，验证了两个DC-DC转换器转换器可以充分地操作。为了验证FCHEV在三种状态下的功率流，有必要限制电流值或占空比，并提出考虑SOC的控制方法。
Several researches on fuel cell hybrid electric vehicle (FCHEV) have been conducted in order to reduce greenhouse effect gas. One of the electric powertrain of fuel cell electric vehicle consists of fuel cell, rechargeable energy storage device, boost chopper and bidirectional chopper. The smaller size of the power converter on fuel cell hybrid electric vehicle is expected. Thus, interleaved configuration has advantage in converter size. This paper shows driving characteristics of an interleaved boost chopper connected to fuel cell and of a bidirectional chopper connected to electric double layer capacitor (EDLC). It is required that the bidirectional chopper is controlled by control method which considers state of charge (SOC) on EDLC. This paper proposes a control method which considers SOC on EDLC, and shows driving characteristics of the choppers for FCHEV in three states. As results of experiment, it is verified that two DC-DC converter converters can be operated adequately. In order to verify the power flow in three states in FCHEV, it is necessary to limit current value or duty ratio and to propose control method which considers SOC on EDLC.
