Embodiment Construction
[0034] This embodiment provides an energy router based on a DC microgrid inverter, such as figure 1 As shown, it includes 3 input ports IN1, IN2, IN3, 3 buck-boost conversion circuits (BUCK-BOOST circuits) Q1, Q2, Q3, 3 diodes D1, D2, D3 and 1 output port OUT. The input end of the voltage conversion circuit Q1 is connected to the input port IN1, the high voltage end of the output end is connected in series with the diode D1, and the output end of the diode D1 is connected to the output port OUT, and the other branches are the same. When using the energy router, each input port can be connected to an external DC power supply, and the output port can be connected to an external DC bus. For example, in this embodiment, the input port IN1 is connected to a photovoltaic power generation device, and the input port IN2 is connected to a fuel cell. , connect the input port IN3 to the battery, and the output port OUT to the external DC bus UR. Understandably, the input port can also b...
