Abstract
A redundant isolating switch control circuit comprises a working power supply, a power input end, a power output end, at least one field-effect transistor, a first transistor, and a second transistor. The field-effect transistor comprises a gate electrode, a source electrode connected to the power input end and a drain electrode connected to the power output end. The first transistor and the second transistor together with the associated circuits form a current mirror circuit. The redundant isolating switch control circuit further comprises a first electronic unit comprising a first connecting end connected to the first base electrode of the first transistor and a second connecting end connected to the second emitter electrode of the second transistor, and a second electronic unit comprising a third connecting end connected to the first collector of the first transistor and a fourth connecting end connected to the gate electrode.
