In the presentation, we propose the construction of the super energy saving ecosystems using power electronics based on widegap semiconductors, as autonomous distributed infrastructure systems which work even in emergency cases like East Japan great earthquake disaster. This proposal consists of (1) R&D of advanced power electronics using widegap semiconductors like silicon carbide (SiC) and (2) the construction of super low loss energy control and communication systems based on such advanced power electronics. By realizing such super energy saving ecosystems, advanced eco-cities resisting a disaster are expected to be built. The proposed ecosystems are also quite effective for preventing global warming and promoting industrial development.
