| titleOfInvention | Self-checking system of frequency converter |
| abstract | The invention discloses a self-checking system of a frequency converter and the frequency converter, which comprises: the detection circuit comprises a first voltage output end and a second voltage output end; the detection result feedback module comprises a detection voltage judgment module and a first exclusive-or logic module, wherein the voltage judgment module is respectively connected with the first voltage output end and the second voltage output end and is used for outputting a corresponding logic level Vout according to the voltages of the first voltage output end and the second voltage output end; and the first exclusive-or logic module is used for carrying out exclusive-or operation on the logic level Vout and the driving signal VG and outputting a fault feedback signal Warn to the main control module. By adopting the technical scheme of the invention, self-checking can be carried out before the frequency converter, and whether the frequency converter is over-current or not can be detected after the frequency converter is started. |
