The maximum power detection unit operates a MOSFET in a power converter circuit and open-circuits both ends of a solar cell panel in the maximum power detection mode. The intercooling turbine section is situated in an intermediate flow path that is inboard of an outer bypass flow path. Incoming radiation incident through the incidence surface of the lens structure is internally totally reflected by the reflecting surface, refracted by the refractive surface and exits the lens structure. In response, the second slave unit will configure itself with the second-lowest slave identifier number such as configuring itself to respond to the second-lowest com line, and so forth.
