1System description

The distributed power generation system is composed of a hydrogenfuel cell stack engine, a power grid-connected inverter, and a power monitoringsystem.

Hydrogen fuel cell engines consume hydrogen to produce electricalenergy. The grid-connected inverter includes DCF and DC/AC. DCF realizes thestable control of the current of the stack and boosts it. DC/AC completes theinverter grid-connecting function and completes the grid-connecting on the 380Vdistribution network side.

2Description of grid-connected inverter

This grid-connected inverter has two main parts DCF and DC/AC. Theinput part of the grid-connected inverter is a fuel cell stack, and the currentof the stack is controlled by DCF; the DCF output is directly connected to thehigh-voltage DC bus, the inverter completes the inversion, and the 380V AC isconnected to the grid through the isolation transformer.

The DCF and DC/AC of the grid-connected inverter have CAN/485communication and are equipped with a touch screen. With active and reactivecontrol functions.

The grid-connected inverter is also equipped with input and outputEMI filters to make it work without electromagnetic pollution.

Due to the use of silicon carbide devices, the conversion efficiencyis high compared to similar products.

The grid-connected inverter is anintegrated design of DCF and inverter, no need to configure a cooling pump, andit is easy to use.
