When the dynamometer is actively running, the three-phase power supply is rectified and fed back into DC power supply to the frequency converter, and the frequency converter inverts the DC power into AC power to drive the dynamometer; when the dynamometer is passively running, the AC power generated by the motor is converted into The direct current is sent to the rectification feedback unit, and the rectification feedback unit converts the direct current into alternating current and sends it back to the grid. The reversibility of electric energy is realized through rectification and inversion between the grid and the motor, thereby achieving the purpose of saving energy.

The operation of the DTC variable frequency inverter system is very simple. Turn the closing switch 90° clockwise, and after hearing a "pop", the closing is in place. Turn the power-on switch 90° clockwise to power on. The power indicator lights up. Click the start button, the running indicator light is on, and it takes 2 minutes for the rectification feedback and the inverter to run. After that, the industrial computer can be used to operate the dynamometer.
After the dynamometer is running, the power-off sequence is: click the start button, the button is self-locking to open, the running indicator light is off, turn the power-on switch 90° counterclockwise, and power-on is off. The power light is off. Turn the closing switch 90° counterclockwise, and after hearing a "pop", the closing switch is disconnected.
