5、 ; Simulink working principle of understanding of the signal-phase voltage regulator circuits with pure resistance of the work load, the use of Matlab's Simulink simulation platform and the Treasury Simulation Model of the signa-phase voltage regulator circuit structure and c
6、ircuit model simulation experiment. Circuit model from AC power, two anti-parallel thyristor, trigger module, load resistance, and composition of the oscilloscope. The results show that the formation of the circuit to generate- a theoretical model of the role of the regulator.
