he paper presents a three-phase rectifier with sinusoidal source current which enables energy to be fed back to the AC supply network. It has been used in a flywheel energy storage system. The principle of operation and control methods of the three-phase rectifier are discussed. The experimental setup employing a DSP controller co-operating with CPLD device is described. Results of experimental investigation for both the steady and transient states are presented in the concluding section.

Abstract Flywheel energy storage system as a new energy source is widely studied. This paper establishes a dynamic model of a single disk looseness and rub-impact coupling hitch flywheel energy storage rotor system firstly. Then dynamic differential equations of the system under the condition of nonlinear oil film force of the sliding bearing are given. Runge–Kutta method is used to solve the simplified dimensionless differential equations. The effect of variable parameters such as disk eccentricity, stator stiffness and bearing support mass on the system are analyzed. With the increase of eccentricity, the range of period-three motion is significantly reduced and the range of chaotic motion begins to appear in the bifurcation diagram. Meanwhile, stiffness of the stator and mass of the bearing support have a significant influence on the flywheel energy storage rotor system.
