Abstract

Disclosed is a bridge type switching apparatus for a power supply. A shell is provided with a positive electrode input terminal, a negative electrode input terminal, a first load terminal and a second load terminal, wherein a first control circuit, a second control circuit, a third control circuit and a fourth control circuit with the same structure are arranged in the shell; each of the first control circuit, the second control circuit, the third control circuit and the fourth control circuit comprises a PNP triode and an N-channel field effect transistor separately; and switch-on or cut-off of different control circuits is realized through connection between the PNP triodes and the N-channel field effect transistors, and the positive electrode input terminal, the negative electrode input terminal, the first load terminal and the second load terminal. According to the bridge type switching apparatus, when a load is connected with a power supply, control circuits of two modules of any polarity are switched on while the control circuits of the other two modules are cut off, so that power supply to the load is realized; meanwhile, the principle is simple, and the bridge type switching apparatus is quite convenient to implement; and in addition, each element is low in cost, and the apparatus cost is reduced.

Description

technical field [0001] The invention belongs to the field of power supply control, and in particular relates to a bridge switching device for a power supply. Background technique [0002] When supplying power to the load, the presence of the power supply is required, but for some loads, it is easy to reverse the connection. In the prior art, the usual solution to the phenomenon of reverse connection is to identify the positive and negative of the load through the identification circuit, so as to realize the correct wiring of the load. The circuits involved in the above methods are complex and costly; and it is troublesome to separate the positive and negative poles when the load is connected to the power supply. Contents of the invention [0003] The invention aims to provide a bridge switching device for power supply with simple structure and convenient use. [0004] In order to solve the above technical problems, the present invention provides the following technical s...
