A current detection circuit (9) is inserted in the circuit passing through the load (6a), and the magnitude of the current passing through the load (6a) is detected, and the magnitude of the applied voltage to the load (6a) K is They are detected by a voltage detection circuit (12), and signals corresponding to their respective magnitudes are supplied to a comparison detection circuit (lO). In this comparison detection circuit (lO), the reference signal, that is, the reference voltage, is compared with the magnitude of the signal (DC voltage) from the above-mentioned current or voltage detection circuit (9) or (12), and the comparison output is 5 so as to be supplied to the base of the transistor (3) mentioned above. Therefore, the oscillation transistor (3) depends on the current flowing through the load (6a) or the voltage applied to the load (6a).
), the current or voltage to this load (6a) is always held constant because the base current for the load (6a) is varied, that is, the feedback circuit is configured. , this can be changed by adjusting the comparison detection circuit (10), for example by adjusting the reference voltage, and can be set to a predetermined value in advance. Therefore, the circuit system that passes through this load (6) is generally called a control system.

In such a case, if it is desired to change the voltage or current of only the non-controlled load (6b), conventionally this has been achieved by varying the oscillation frequency in the blocking oscillation circuit. In such a case, a circuit for varying the frequency must be installed separately, which increases costs, and in the so-called automatic oscillation system shown in Figure 1, all the parts that vary the constant are fixed. Therefore, it is possible to vary the frequency without losing the characteristics of the excitation oscillation method.5
It was difficult to configure.

To explain the operation of such a configuration, the voltage waveform between the collector terminals of transistor (3) is shown in Figure 3.
, the current waveform of this collector is shown in FIG. 3Bk, and the anode side of the diode (7a), that is, the point. The voltage and pressure waveforms are shown in Figure 3C.
Each K is shown. Of the output waveform shown in Fig. 3C, the voltage on the positive side contributes to the load (6a) of the control system, and this voltage is the period during which current flows through the collector of the transistor (3). Determined by The period during which no current flows through the collector of the transistor (3) is related to the negative Ill voltage shown in FIG. 3Cm, and if this voltage contributes to the non-controlled load (6b), it becomes K.

Therefore, the control in the feedback system described above is performed only on the load (6a).In such a state, if the resistance value of the variable resistor (11) is changed and increased, the transistor (3) It works to lengthen the period in which the collector current flows, and when the resistance value is decreased, it works to shorten the period in which the collector current flows. Therefore, by changing the flow period of the collector current of the transistor (3), the voltage waveform can be changed as shown by the dotted lines in Figure 3 and C.
Based on this, the current flowing through the non-controlled system or the load voltage in the non-controlled system can be changed within a certain range. In this case, the voltage or current of the control system is always controlled to be constant by the feedback system described above, and therefore does not change.
