Abstract

The present invention relates to a switch circuit of power switching. The switch circuit provided by the invention comprises: a logic gate conversion module, a first driving module, a second driving module, a first switch module and a second switch module. The logic gate conversion module is configured to convert input logic control signals into first logic driving signals and second logic driving signals; the first driving module is configured to output first switch signals and second switch signals according the first logic driving signals; the second driving module is configured to output third switch signals and fourth switch signals according to the second logic driving signals; and the first switch module is configured to output voltage to a load under the control of the first switch signals and the second switch signals, or the second module is configured to output voltage to the load under the control of the third switch signals and the fourth switch signals. According to the invention, the problem of the system fault caused by simultaneously conducting diverter switches because of the disordering of control signals is solved, the complete separation of the control signals and a heavy current is realized, and the weight of the system device is reduced; and moreover, the switch circuit of power switching has an important practical value.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to a power switch circuit. Background technique [0002] The main function of the sonar transmitter is to generate a power signal with a specific form, which is actually a power conversion system, which is responsible for converting the DC power into a certain frequency of AC power for the load (transducer). For a specific load (transmitter), the size of the power signal is determined by the input voltage. For a transmitter with two power signals for high-power transmission and low-power transmission, it is required that the large and small power switch has a small power on the basis of high stability and reliability. switching power loss and high switching speed. [0003] For high-power transmission (several kilowatts) signals, the dry circuit current is nearly 100 amperes, which determines that conventional switches are no longer applicable. At present, the soli...
