Problems solved by technology

[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

Abstract

The invention discloses a drive control method for a multiple rectification circuit, which is applied to an FPGA chip and includes: receiving 6 input pulses; determining 12 or 24 output pulses according to the 6 input pulses, and passing the determined The output pulses drive and control the multiple rectification circuit; wherein, within one cycle, each output pulse includes k consecutive short pulses, k is a positive integer and is at least 2. By applying the method provided by the invention, the thyristors in the multiple rectification circuit can be triggered more effectively. The invention also discloses an FPGA chip and a drive control system for multiple rectification circuits thereof, which have 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...
