Abstract
PURPOSE:To ensure the steady generation of the saw-tooth waves by detecting the fixed voltage is secured in the fixed time after the rise of the saw-tooth wave via the saw-tooth wave generator circuit which can vary the inclination of the saw- tooth wave and then feeding the detection output back to the generator circuit as the control signal. CONSTITUTION:Output voltage V1 of reference voltage generator circuit 1 is applied to one input of voltage comparator circuit 2, and output V3 of the saw-tooth wave sent from saw-tooth wave generator circuit 3 which rises up in synchronization with reference voltage V2 is applied to the other input of circuit 2. And pulse V4 is delivered when the coincidence is obtained between voltage V1 and output V3 of the saw-tooth wave sent from circuit 2. At the same time, pulse V4 is generated through detection that the fixed voltage is obtained in the lapse of the fixed time since the rise of V3. The phase difference between pulse V4 and 2nd reference voltage V5 is detected through phase difference detector circuit 4, and signal V6 corresponding to the phase difference is delivered from circuit 4. This signal is then converted into DC voltage V7 through LPF5, and voltage V7 is fed back to circuit 3 to give correction to the inclination of output V3 of the saw-tooth wave.
