Abstract

PURPOSE: To reduce the power loss of the switching element by giving a comparison between the voltage corresponding to the current flowing to the coil of electromagnetic valve and the control voltage calculated previously and then giving the control to the conduction period of the current.
CONSTITUTION: When the signal of output terminal b of comparator 2 is on, transistor Tr7 conducts and the current flows to coil 4 of electromagnetic valve. Integrator 15 performs the integration with the ratio according to the deviation between the control input voltage and the detection voltage of terminal c and based on the control input voltage of terminal d which is calculated previously, and then generates the output to output end e. Comparator 2 gives a comparison between the integration output and the triangular wave output given from oscillator 10 and then delivers the high level signal when the integration output is large. For instance, when the terminal voltage of detection resistance 6 is low compared with the control input voltage, the output of integrator 15 increases in terms of average. As a result, the ON time duration increases for the output of comparator 2, and accordingly the conduction time of Tr7 also increases to increase the current flowing to coil 4.
