Problems solved by technology
[0006] (1) Too many auxiliary power supplies make the system complex;
[0007] (2) Technical problems of frequency and duty cycle of pulse transformer isolation transmission control signal
[0010] The pulse transformer designed for pulse width and pulse frequency has the problem of limited signal transmission; at the same time, the signal transmitted through the pulse transformer will cause delay and distortion, which requires a shaping circuit. Generally, the shaping circuit needs an additional auxiliary power supply with isolation. For A single-tube drive requires two magnetic components, which has the problem of complex structure and large volume of the drive system
Double-edge modulation technology can be used to solve the former problem, but it has the problem of edge identification; the number of magnetic components can be reduced through magnetic circuit integration, but it has the problem of magnetic circuit decoupling

Description
technical field [0001] The invention belongs to the technical field of power electronics, in particular to a function-integrated edge modulation IGBT / MOS drive system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Isolation drive is an important part of the secondary development and application of power switching devices, and it is an important guarantee for the safe operation of power switching devices. For a long time, the drive circuit has been plagued by two major problems. One is that there are too many auxiliary power supplies, which makes the system complex; the other is the technical problem of pulse transformer isolation and transmission control signal frequency and duty cycle limitation. After the third-generation semiconductor power switching devices gradually enter the application market, the topology of the converter is developing towards integration and simplification, and the problem...
