Thermomagnetic generator device and energy converting method |
摘要 |
A generator device for converting thermal energy to electric energy. A magnetic circuit includes at least a portion made of a magnetic material. A temperature-varying device varies the temperature in the portion made of the magnetic material alternately above and below a phase transition temperature of the magnetic material to thereby vary the reluctance of the magnetic circuit. A coil is arranged around the magnetic circuit, in which electric energy is induced in response to a varying magnetic flux in the magnetic circuit. A magnetic flux generator generates magnetic flux in the magnetic circuit. A controllable electric circuit device is connected to the coil and a control device controls the controllable electric circuit device. |
