Abstract
PURPOSE:To contrive to reduce distortion of wave form of output and to reduce output impedance of a high-frequency switching inverter by a method wherein a part of output of the inverter is fed back to an amplifying circuit through a feed back circuit. CONSTITUTION:Signals obtained by performing amplitude modulatin in an amplitude modulating circuit 15 on a sine wave sent from a sine wave generating circuit 14, and triangular waves or saw tooth waves sent from a triangular wave or saw tooth wave generating circuit 19 are performed with phase modulation respectively in comparators 20a, 20b, a switching circuit 2 is made to perform switching by the output signals of the comparators to obtain higher harmonic signals, and moreover the signals thereof are demodulated in a demodulating circuit 8 by synchronizing rectification making synchronizing signals sent from a frequency dividing circuit 13 as the reference to convert into the sine wave and to obtain the output of the inverter. A part of the output of the inverter is fed back to the amplifying circuit 18 through the feedback circuit 21. Accordingly because distortion of wave form of the AC output is improved and output impedance is reduced, transient characteristic to be generated by fluctuation of load can be improved.
