The drive has a hybrid power factor correction module for controlling a voltage step-up module (40) and including a digital circuit (30) integrated in a processing unit, and an analog circuit (20). A voltage regulator module of the digital circuit provides a correction signal from a measurement signal (46) of a regulated bus voltage (45). The analog circuit provides a control signal (25) to the module (40) from the measurement signal and the correction signal. |
