Abstract
A kinetic energy recovery system with flywheel includes a flywheel doubly-fed electric machine, an electric motor, a drive circuit and a controller. The flywheel doubly-fed electric machine has a primary side coil and a secondary side coil. The electric motor has a phase coil connected in series with the primary side coil. The drive circuit has an AC/DC circuit and a DC/AC circuit, wherein the AC end of the AC/DC circuit is coupled to the primary side coil; the AC end of the DC/AC circuit is coupled to the secondary side coil. The controller is configured to manipulate a frequency and a phase of output voltage and output current of the secondary side coil, thereby controlling the frequency and phase of a voltage and a current output from the primary side coil, thereby recovering a kinetic energy of the electric motor or providing the kinetic energy to the electric motor.
