[0003] In the prior art, when the trigger pulse is input to a certain thyristor, a single-pulse trigger is adopted, that is, within one cycle, the thyristor of this line will receive a pulse signal, so that the conduction state of the thyristor changes, but Due to interference and other factors, sometimes the thyristors fail to turn on, which makes the multiple rectification circuit work abnormally, and because the multiple rectification circuit needs as many as 12 or 24 thyristor trigger pulses, this abnormal situation occurs more likely

The invention discloses a driving control method of a multiplex rectifying circuit, which is applied in an FPGA chip. 12 or 24 output pulse are determined according to 6 input pulses, so as to drive and control the multiplex rectifier circuit through the determined output pulses. Wherein, in one period, each output pulse comprises successive k short pulses, k being a positive integer and at least2. By using the method provided by the invention, the thyristor in the multiplex rectifier circuit can be triggered more effectively. The invention also discloses a driving control system of an FPGA chip and a multiplex rectifying circuit thereof, which has corresponding technical effects.
Description
technical field [0001] The invention relates to the technical field of power electronics, in particular to a drive control method and system for an FPGA chip and multiple rectification circuits thereof. Background technique [0002] Multiple rectification circuits refer to the multiple connection of several rectification circuits. On the one hand, it can increase the overall power capacity of the device, and on the other hand, it can reduce the interference of harmonics and reactive power generated by the rectifier device to the power grid. Existing multiple rectification circuits generally require as many as 12 or 24 thyristor trigger pulses. [0003] In the prior art, when the trigger pulse is input to a certain thyristor, a single-pulse trigger is adopted, that is, within one cycle, the thyristor of this line will receive a pulse signal, so that the conduction state of the thyristor changes, but Due to interference and other factors, sometimes the thyristors fail to tur...
