ELECTRONIC SWITCH DEVICE FOR CONTROLLING A HIGH POWER LOAD SUPPLY IN AN AUTOMOBILE

摘要

The invention relates to a switch device (21) for controlling the supply of an electric load (25) from a power source, the power source supplying an energy used for driving an automobile. The device is a static switch device. The static switch comprises: two main thyristors (41) mounted in a tumbled manner and in parallel on a line connecting the power source to the electric load; at least one first capacitor (40); a means (25, 43, 44) for charging the first capacitor; and a means (43, 44) for connecting the first capacitor to the terminals of the main thyristors, the connection of the first charged capacitor to the main thyristor terminals blocking the main thyristor at the passing state.
