The present disclosure relates to a driving circuit and method, and a frequency converter, a device and a computer-readable storage medium. The circuit comprises: a rectifier unit comprising a first input end and an output end, the output end of the rectifier unit being connected to the input end of an inverter unit, and the line between the rectifier unit and the inverter unit being connected to the second input end of the rectifier unit; a first switch disposed between the first input end of the rectifier unit and the output end of the inverter unit, and used for controlling, by means of turning off or turning on, a driving circuit to switch between a series mode and a parallel mode, the inverter unit, the output end of the inverter unit being connected to a load; and a capacitor connected in parallel between the rectifier unit and the inverter unit. By means of the present disclosure, the switching of the series and parallel modes of the driving circuit is implemented, so that the idle rectifier unit is transformed into a standby inverter unit, and thus can be fully utilized.
