Abstract: PURPOSE: To improve the efficiency of a power unit and reduce the size of the unit by constituting a switching regulator by using a plurality of horizontal synchronizing pulse trains having different frequencies so that the regulator can work in a plurality of display modes. CONSTITUTION: A horizontal synchronizing pulse train having a selected frequency is supplied to a waveform shaping circuit 2 through a line 11. An automatic frequency control circuit AFC3 incorporates an oscillation circuit 3A and a synchronizing circuit 3B and, since the saw tooth wave generated from the circuit 3A is corrected to a saw tooth wave having a frequency which is a multiple times as high as that of the horizontal synchronizing pulse train impressed upon the circuit 3B, the circuit 3B becomes synchronous to the frequency of the horizontal synchronizing pulse impressed upon the circuit 3B by generating a feedback signal on a line 13A. The power control circuit 8 of a switching regulator type power source circuit 9 receives a pulse from a line 16 and a feedback signal from a line 17 and generates a switching pulse on a line 18.  Therefore, a power unit can operate at a frequency which is several times as high as a plurality of horizontal synchronizing frequencies and, moreover, synchronously and the principal design parameters can be selected so that the optimum operating condition can be obtained.
