Abstract: A driving circuit for electronically switched motors is provided. The driving circuit includes a supply voltage rectifying stage for providing a rectified supply voltage, first switching means for switching state based on output of a first control block, magnetic means for providing a magnetic flux according to the state of the first switching means, transmission diodes for transmitting an exciting current that flows through the magnetic means, first energy storing means for storing the exciting current, an energy return stage for transferring the energy stored in the first energy storing means to the rectifying stage, and energetic conversion means for receiving the energy stored in the energy storing means through second switching means controlled by a second control block, so as to provide a current as sinusoidal as possible.
