Beschreibung
Zusammenfassung:The utility model discloses an FPGA-based frequency conversion AC power-supply control apparatus comprising an inversion main circuit, an LC filter circuit, a load and an FPGA control unit, wherein the inversion main circuit consists of a full-bridge rectification circuit, a DC-DC circuit and an inversion bridge circuit; the LC filter circuit is connected with the inversion bridge circuit; and the FPGA control unit is respectively connected with the DC-DC circuit and the inversion bridge circuit by a driving isolation circuit. A DC sampling circuit connected with the FPGA control unit is mounted between the DC-DC circuit and the inversion bridge circuit. An AC sampling circuit connected with the FPGA control unit is mounted between the LC filter circuit and the load. The FPGA control unit is connected with a temperature-detection and heat-dissipation circuit. The AC power-supply control apparatus provided by the utility model utilizes an FPGA to generate an SPWM waveform to drive an inversion bridge in a freq
