Problems solved by technology
This detection generally requires the use of a multivibrator, but since the multivibrator can only control the cycle and cannot control the adjustment of the pulse width, it is generally connected to a pulse generator, but the existing pulse generator The cost is high, and most of them are processed by integrated chips, which is not conducive to various experimental needs in the research and development stage

Description
Technical field: [0001] The invention relates to a double pulse generating device, in particular to a double pulse generating device used in wind power technology. Background technique: [0002] Wind power technology is the technology of using wind energy to generate electricity, mainly relying on the manufacture of wind energy generators. Because wind energy is a renewable and environmentally friendly energy source, the development of wind power technology is the main development strategy of many countries today. The core part of modern wind power technology is to drive the insulated gate bipolar transistor (Insulated Gate Bipolar Transistor, referred to as IGBT) to switch off to complete the control of the entire system by the converter. Before the product is put on the market, it is generally necessary to test its various parts, and one of the key points of testing is to simulate the driving system signal to realize the test of the driving link. This detection generally...
