JBZ6500 series high power and high precision can feed back DC electronic load. The main control of the system is realized by DSP+FPGA, which ensures the rapid response of the system, high precision of control and diversification of measurement parameters. The system adopts DC-DC, DC-AC bi-directional conversion two-level or threelevel structure, which can effectively stabilize the fluctuation of bus voltage in sudden application, thus improving the dynamic response time of the whole machine output. DC-DC converter adopts high frequency inverter circuit, with wide input voltage range and fast response. The DC-AC converter adopts SVPWM three-phase full-bridge inverter technology, and the load absorbs energy to effectively feed back to the grid. The grid connected harmonic pollution is small, the control is simple, the efficiency is high, the load characteristics are good, and the load absorbs energy to feed back to the grid.
