The design of the sampling circuit of the control system for the magnetic control reactor based on DSP
摘要
Abstract
In the control system of the magnetic controlled reactor ( MCR) , it is necessary to sample the current and voltage in the grid .In view of the difficulty in accurately measuring high voltage and large current in real time , the design of the sampling of high voltage and large current in the power system was introduced in detail in this paper , and the ac sampling hardware solution based on DSP was proposed .At the same time , the phase compensation circuit and zero crossing detection circuit were designed , and the system test results of the circuits were provided .The results showed that the proposed scheme solved the sampling problems for voltage and current in the control system of MCR and the problem of datum point selection for the thyristor trigger signal .关键词
