Power tube driving device with drive pulse regulating function

Abstract

The invention belongs to the signal processing field, and provides a power tube driving device with a drive pulse regulating function. The power tube driving device with the drive pulse regulating function comprises a shortest turn-on time processing module, a longest turn-on time processing module, a shortest turn-off time processing module and a turn-on time deviation processing module. Through the power tube driving device with the drive pulse regulating function, high level and low level in each period of a drive pulse signal of a power tube can be processed in an optimized mode, the widths of the high level and the low level in each period are enabled to be maintained in a reasonable interval, and therefore power consumption of the power tube is effectively lowered, safe and reliable operation of the power tube is guaranteed, whether a system works normally can be judged according to the width difference of the high level in two adjacent periods, when the width difference of the high level exceeds a turn-on time deviation threshold, the system is judged to be in an abnormal state, and a drive circuit is controlled to turn off the power tube at the same time so that the safety of drive control of the power tube is improved.

Description

technical field [0001] The invention belongs to the field of signal processing, in particular to a power tube drive device with a drive pulse adjustment function. Background technique [0002] At present, as power tubes are widely used in various fields, the requirements for their driving circuits are also getting higher and higher. The commonly used drive circuits provided by the prior art are all composed of discrete devices, which have complex structures, high costs, and large circuit volumes; in addition, the prior art also provides an integrated circuit chip, although it solves the problem of large circuit volume problem, but it often does not deal with the high and low level time of the driving pulse or does not deal with it comprehensively enough, which will cause the power tube to have too small switching gap time, too long conduction time, and adjacent Inconsistencies in the turn-on time of the cycle will lead to increased power consumption and heat generation of t...
