Abstract

The invention provides a linear motor generator power supply which comprises double electromagnets placed at two ends of a body, and a tubular linear generator is placed in the middle to form two cylinders A and B. An electromagnet excitation coil a is energized to force a permanent magnet array free piston mover to perform mechanical movement to the B cylinder, therefore, magnetic lines cut a linear generator stator winding and an electromagnet excitation coil b, induced current is generated, a group of super capacitor modules is charged after rectification and voltage regulation, another group of super capacitor modules discharges to the electromagnet excitation coil a, and balance current is used for a load. Conversely, the electromagnet excitation coil b is energized, the linear generator stator winding and the electromagnet excitation coil a generate induced current, the electromagnet excitation coil a or b is alternately conducted in a pulse way, and the linear generator stator winding and the electromagnet excitation coil a or b generate continuous induced current. The two groups of super capacitor modules are alternately and automatically switched between charging and discharging, the voltage cycle, conversion and recombination required for linear motor generator driving can be achieved, balance voltage is outputted from the load. The linear motor generator of the present invention provides a regenerable power source.

Description

technical field [0001] The invention relates to the technical fields of new energy, regenerative power supply, motor and generator, in particular to a linear motor generator power supply, which becomes a renewable power supply. Background technique [0002] The accompanying energy security and environmental pollution are two of the most thorny bottlenecks. Petroleum security, resource shortage, and harmful substances emitted by the exhaust of automobiles during driving damage the environment and human health. [0003] However, electric vehicles have hybrid, plug-in hybrid, fuel cell, pure electric vehicles and other modes, limited by the level of power battery technology and charging technology, there are energy density, cruising range, charging speed, construction of charging stations, etc. Restricting factors have become a bottleneck in the development of pure electric vehicles. In view of this, there is an urgent need for a generator or charging method for renewable power...
