Abstract

PURPOSE: To avoid the frequent on/off actions of the output circuit, by securing the blind sector within the hysteresis width of the control system.
CONSTITUTION: The comparison input (e) increases as the time elapses through the integral networks CI and RI even though the deviation ε is lower than the response level of the comparator 3, and thus the comparator 3 can be turned on. When the deviation ε is small enough, both the comparators CP1 and CP2 are turned on in the blind sector setting circuit 6 with the subsequent switch SW5 turned off. Thus no deviation ε is applied to the integral network. And if the deviation ε is kept small enough, the off-state of the comparator 3 is kept. And if the width of the blind sector is set to the value equivalent to the electric power capacity of the output circuit, the offset can be reduced to reduce the on/off frequency of the output circuit. As a result, the output circuit can be protected well.
