Abstract
PURPOSE:To make the necessitated reactive current to flow always regardless of output freqency, and to make a high frequency inverter to perform stable operation by a method wherein delay time of an output current in relation to an output voltage is regulated properly corresponding to output frequency of the inverter. CONSTITUTION:The voltage of tank on the load side taken out from a transformer TF is led to a comparator 5, and zero points at every half phases are taken out, and when it is in the positive half wave period, a flip-flop 10 is made to reset, and when it is in the negative half wave period, a rectagular signal is outputted through a diode D2. The rectangular signals thereof are led to a monostable multivibrator 6, the fectangular signals sent out from the monostable multivibrator 6 are integrated in an operational amplifier 7, and are compared to be amplified in an operational amplifier 8. Output of the operational amplifier 8 is applied to a relaxation oscillation circuit 9. Accordingly timing of a gate signal to be sent out from a gate signal generating circuit 11 is controlled as to make the necessitated reactive current to flow regardless of output frequency of the inverter.
