<p>PROBLEM TO BE SOLVED: To provide a current amplification device capable of improving efficiency of current amplification further, and of downsizing the device.SOLUTION: A current amplification device 10 comprises a rotary electric machine GM including a DC motor M driven by a DC power supply 13, and first and second DC power generators G1 and G2 rotated and driven by the DC motor M. Since the current amplification device 10 outputs a current from the DC power supply 13 and currents from the first and second DC power generators G1 and G2 to the exterior, an efficient current amplification can be achieved. In the rotary electric machine GM, the DC motor M and the first and second DC power generators G1 and G2 are arranged in coaxial positions, and rotation shafts X of the respective rotors RT1 to RT3 are directly coupled and operated together.</p> |
