Multi lateral compensation type high power density electromechanical energy convertor

A multilateral compensation high power density mechanical and electrical energy converter relates to the filed of a pole and solves problems existing in the traditional flywheel accumulation system that the voltage regulation factor output by a generator is large; and the DC bus voltage is determined by a power supply and can not be adjusted arbitrarily, thereby the applied range of a system is limited. In the invention, a duplex winding composite excitation synchronous machine is formed by changing a permanent magnet of the original composite excitation synchronous machine and adopting a duplex winding. The duplex winding composite excitation synchronous machine is coaxially connected with an inertia flywheel; two sets of armature windings of the duplex winding composite excitation synchronous machine are respectively an input winding and an output winding, and are respectively connected with an output end of an inverter and an alternating input end of a rectifier; and two DC excitingwindings of the converter are connected in series, and then are connected into a DC bus output by the rectifier. The multilateral compensation high power density mechanical and electrical energy converter has the advantages of simple structure, high reliability, low voltage regulation factor, high efficient, big power density, and the like.
