<p>A semiconductor DC transformer (1) comprises: a plurality of semiconductor electricity-to-light conversion structures (10) connected in series for converting input electric energy into optical energy; and a plurality of semiconductor light-to-electricity conversion structures (20) connected in series for converting input optical energy into electric energy, in which the number of the semiconductor electricity-to light conversion structures (10) is different from that of the semiconductor light-to-electricity conversion structures (20) so as to realize a DC transformer, and a working light spectrum of the semiconductor electricity-to-light conversion structures (10) is matched with that of the semiconductor light-to-electricity conversion structures (20).</p> |
