Embodiment Construction
[0022] The bypass line proposed by the present invention mainly includes a thyristor, a first impedance element and a second impedance element. The thyristor is connected in parallel with the electronic element, and the first impedance element and the second impedance element are also connected in parallel with the electronic element after being connected in series. The gate electrode of the thyristor is further coupled between the first impedance element and the second impedance element, wherein the terminal voltage of the electronic component can be divided by the first impedance element and the second impedance element, as the thyristor gate voltage. When an electronic component fails and causes an open circuit, its terminal voltage is the largest, and the gate voltage after voltage division will be greater than the critical voltage of the thyristor, thereby triggering the conduction of the thyristor. In this way, the current that should originally pass through the failed ...
