Automobile solar-powered ventilation device has microprocessor for matching operating parameters of electric fan to radiation characteristics of solar generator

摘要

The ventilation device has an electric fan (14) supplied with power via a solar generator (10), with an impedance converter (12) and an electronic control stage (18) inserted between them. The operating parameters of the electric fan are matched to the radiation characteristics of the solar generator via a microprocessor (22) provided with a separate current supply (24) independent of the electronic control stage.
