[0089] The control method proposed by the present invention is tested on a 20kW three-phase grid-connected inverter prototype. The test parameters are shown in Table 1 below.
[0090] Table 1
[0091]
[0092] Detect experimental waveform by oscilloscope, analyze experimental data by accurate power analyzer, adopt the control method that the present invention proposes, gained experimental data: THD<1.5% (full load, 20kW), failure probability (inverter uninterrupted operation 10 days during test , the ratio of downtime to total time) is less than 2.5%.
[0093] The screenshot of the experiment is as follows:
[0094] (1) When the inverter is running stably, the output current waveform of the inverter is detected under full load (20kW) and light load (1kW), and the full load (20kW) is as follows Figure 5 As shown, light load (1kW) such as Image 6 shown. Depend on Figure 5 , Image 6 It can be seen that the inverter output current control method proposed by the prese...
