Description
Technical field
The present invention relates to a kind of multi-power source voltage regulating circuit.
Background technology
In DC power system, regulator mainly contains following several: (1) adopts the regulator of " manually direct current voltage regulator "; (2) adopt the regulator of " electric DC voltage regulator "; (3) adopt the direct-current voltage automatic adjusting device of silicon diode step-down mode; (4) adopt the direct current voltage reulation device of " transistor DC Switching Power Supply "; (5) adopt the stepless pressure regulation device of high frequency chopping technology.
Above several regulator, although front 2 kinds simple and reliable, adjustable range is wide, troublesome poeration, the waste cable, must have the people could operate at the scene, can not satisfy current needs, so use fewer, also not general; Use conveniently for the 3rd kind, safe and reliable; The 4th kind is not suitable for electromagnetic operating mechanism, is only suitable for spring operation and does in the transformer station of mechanism; And the 5th kind---electrodeless buck chopper technology is not also very ripe, often breaks down, and therefore the direct-current voltage automatic adjusting device of employing " silicon diode step-down mode " can satisfy the demand of pressure regulation better.
