The invention relates to a power conversion device of a fuel cell system and the fuel cell system adopting the power conversion device. The conversion apparatus includes a communication unit configured to receive a power regulation command from a stack of the fuel cell system, the power regulation command including a requested draw value instructing the power conversion apparatus to draw electrical power from the stack and at least one limit constraint value related to a power draw constraint; and a control unit configured to determine a target draw value for drawing electrical power from the stack based on the requested draw value and at least one limit constraint value.

    本发明涉及燃料电池系统的功率变换设备及采用该变换设备的燃料电池系统。该变换设备包括通信单元,配置为从所述燃料电池系统的电池堆接收功率调控命令,该功率调控命令包括指示所述功率变换设备从所述电池堆汲取电功率的请求汲取值以及与功率汲取约束相关的至少一个极限约束值;以及控制单元,配置为基于所述请求汲取值与至少一个极限约束值确定从所述电池堆汲取电功率的目标汲取值。
