Movable parallel water-hydrogen power generation inverter system

Abstract

The invention provides a movable parallel water-hydrogen power generation inverter system. The movable parallel water-hydrogen power generation inverter system comprises an inverter, a PWM controllerand a power optimization module, wherein the inverter is connected with a fuel cell and a load, and is used for inverting the electric energy generated by the fuel cell and then supplying the electric energy to the load to be used; the PWM controller is used for sending an adjusting signal to the inverter; the inverter adjusts the output voltage of the fuel cell according to the adjusting signalso as to maximize the output power of the fuel cell; the power optimization module is used for acquiring the state parameters of the fuel cell, determining an output voltage corresponding to the maximum power of the fuel cell according to the state parameters, and controlling the PWM controller to send out an adjusting signal according to the determined output voltage, so that the output power ofthe fuel cell reaches the maximum under the control of the PWM controller. The inverter system can adjust the output voltage of the fuel cell, so that the output power is kept to be maximum in the power generation process of the fuel cell so as to maximize the power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of water-hydrogen power generation, in particular to a mobile parallel water-hydrogen power generation inverter system. Background technique [0002] The water hydrogen generator is a kind of equipment that uses methanol aqueous solution as a raw material to feed the hydrogen production system, and the high-purity hydrogen produced is fed to the fuel cell for electrochemical reaction, and then directly converts chemical energy into electrical energy. Its energy conversion efficiency is high. There is no noise pollution, and only emits water and a small amount of carbon dioxide, which realizes real energy saving and environmental protection, so it is considered to be the mainstream of new energy power development. [0003] The fuel cell is responsible for power generation in the water-hydrogen generator, through which the chemical energy of the raw material is converted into electrical energy and output to el...

Problems solved by technology

[0004] At present, in the process of fuel cell power generation, it is impossible to control the output voltage of the fuel cell to the size that can maximize the output power. At the same time, the output voltage of the fuel cell may be affected by some factors and change at any time. The above two points The reason is that it is impossible to maintain the maximum output power of the fuel cell, so it is impossible to maintain the maximum power generation efficiency of the fuel cell
