Abstract

PURPOSE: To use only one operational amplifier and make the relation between a control signal and a turn-on phase angle linear, by providing an operational amplifier which starts the integration of a constant input current in response to a signal from a zero point detector.
CONSTITUTION: A sine-wave AC voltage is applied to the zero point detector 130 to produce a rectangular-wave signal. The integrating action of the operational amplifier 122 is started at the time of falling of the rectangular-wave signal. The resistance ratio of a positive input resistor 120 to a negative input resistor 119 for the control signal Vi to the operational amplifier 122 is equalized to that of a voltage dividing resistor 121 to a bias resistor 114 to keep the input current to the operational amplifier 122 constant. The voltage of the control signal is altered to change the phase of pulse generation. Thus, integration, resetting and comparison can be effected by only one operational amplifier, and the relation of the control signal to the turn-on phase angle is made completely linear.
