Filed: 1994-07-08
Abstract: PURPOSE:To reduce a higher harmonic wave component contained in an output waveform to be ouputted to a load by rectifying a signal from the secondary side terminal of a transformer while alternately repeating the forward and backward phase signals by turning on/off a switching element, and adding it later. CONSTITUTION:Corresponding to the driving signal of a driver part 2, a voltage resonance switch part 8 alternately performs ON and OFF switching operations and converts ON and OFF voltages to resonant waveforms. The outputs of switching elements Q1 and Q2 in a switch part 8 are respectively connected to the primary side terminal of a transformer 6 and according to the push/pull operations of the elements Q1 and Q2, the transformer 6 transmits those signals to a secondary coil. Then, the output signals of the transformer 6 are connected from the secondary side terminal to a rectifying/synthesizing part 7 so that they can be mutually added with opposite phases. Therefore, since the signals from the transformer 6 are rectified/added by the rectifying/adding part 7 after the forward and backward phase signals are mutually repeated according to the ON/OFF of the elements Q1 and Q2 at the switch part 8, the higher harmonic wave component contained in the output waveform to a load 5 can be reduced.
