Suspension control power supply circuit based on hydrogen fuel cell
The invention discloses a suspension control power supply circuit based on a hydrogen fuel cell. In the circuit, a timer circuit is connected with a hydrogen fuel cell module, and a voltage stabilizing unit is connected with the hydrogen fuel cell module, an energy storage module and a suspension control module. When the suspension system is in a rated working condition, the hydrogen fuel cell module is switched to a constant power mode, the working state of the hydrogen fuel cell module is selected according to the capacity condition of the energy storage module, and when the working state is switched, the timer circuit is reset to start timing so as to obtain the corresponding working state duration time; and the working state duration and the corresponding output voltage change value are controlled to ensure that the power supply voltage is in a stable state for the suspension system. In addition, the working state of the hydrogen fuel cell is selected according to the capacity of the energy storage module, and frequent state switching of the energy storage module and the hydrogen fuel cell module caused by suspension control fluctuation is avoided. Under the peak working condition, the energy storage module is switched to the discharge state to adapt to the suspension system in real time, and the defect of slow dynamic response of the hydrogen fuel cell is overcome.
本发明公开一种基于氢燃料电池的悬浮控制供电电路，所述电路中的计时器电路连接氢燃料电池模块，稳压单元连接氢燃料电池模块、储能模块以及悬浮控制模块。当悬浮系统处于额定工况，氢燃料电池模块切换至恒功率模式，并根据储能模块的容量情况选择氢燃料电池模块的工作状态，切换工作状态时，计时器电路复位开始计时以获取对应的工作状态持续时间，控制工作状态持续时间和对应的输出电压变化值确保对于悬浮系统来讲供电电压处于稳压状态。此外根据储能模块容量选择氢燃料电池的工作状态，避免因悬浮控制波动引起储能模块和氢燃料电池模块频繁切换状态。在峰值工况下，储能模块切换至放电状态实时适应悬浮系统，弥补了氢燃料电池动态响应慢的缺陷。
