PURPOSE:To simplify the constitution and to control the power supply to a load over a broad range, by controlling the power supply to the load with the control of an auxiliary switch element in a switching type power amplifier utilizing the voltage resonance waveform. CONSTITUTION:Auxiliary switch elements 4, 6, are connected in series to either or both of the 1st inductor 5 for energy storage of the flyback pulse due to resonance and the 2nd inductor 7 for smoothing current of the forward pulse in addition to a main switch element 2 for the voltage resonance type switching. Further, the power supply to the load 10 is controlled by controlling the conduction width of the auxiliary switches. |
