As the figure shows, this circuit uses the semiconductor transistor instead of the charging resistance R, and this circuit adds the control voltage Vi on the base electrode of the transistor, when the Ui changes, the collector electrode current IC of the VT1 will change too. When the IC increases, the trigger pulse moves forward; when the IC decreases, the trigger pulse moves backward to achieve the purpose of the phase shifting.
