Abstract
Extra low consumed power suspension in gravitational field is achieved in a power-saving solar photovoltaics magnetic suspension system with a zero-power controller. The zero-power magnetic suspension system needed power becomes statically zero. A fabricated conventional system used 290[mW] total consumed power for the static suspension of 90[g] floator mass. The photovoltaic cells used in the apparatus had a maximum power capacity of about 2[W] in summer sunlight. Therefore, this system can supply the power necessary for static suspension in sunlight. However, most of the power were used in peripheral devices including the displacement sensor. A dedicated power-saving peripheral devices are newly fabricated for this system. The power is reduced from 290[mW] to 50[mW]. The new system achieves stable suspension even under the illuminance of the fluorescent lamp.
